NAME

       patchwork - filter for drawing clustered graphs as treemaps

SYNOPSIS

       patchwork  [-(G|N|E)name=value]  [-Tlang]  [-llibfile]  [-ooutfile]  [-O]  [-P]  [-v] [-V]
       [files]

DESCRIPTION

       patchwork draws clustered graphs using a squarified treemap layout.  As  input,  it  takes
       any graph in the dot format. Each cluster is given an area based on the areas specified by
       the clusters and nodes it contains. The areas of nodes and empty clusters can be specified
       by the area attribute.  The default value is 1.

       The  root  graph  is  laid  out as a square. Then, recursively, the region of a cluster or
       graph is partitioned among its top-level nodes and clusters, with  each  given  a  roughly
       square subregion with its specified area.

OUTPUT FORMATS

       Patchwork  uses  an  extensible  plugin mechanism for its output renderers, so to see what
       output formats your installation of patchwork supports you  can  use  ``patchwork  -Txxx''
       (where  xxx  is  an  unlikely  format)  and  check  the warning message.  Also, The plugin
       mechanism supports multiple implementations of the output formats.  To see  what  variants
       are  available,  use, for example: ``patchwork -Tpng:'' and to force a particular variant,
       use, for example: ``patchwork -Tpng:gd''

       Traditionally,  patchwork  supports  the  following:  -Tps  (PostScript),   -Tsvg   -Tsvgz
       (Structured  Vector  Graphics), -Tfig (XFIG graphics), -Tmif (FrameMaker graphics), -Thpgl
       (HP pen plotters), and -Tpcl (Laserjet printers), -Tpng  -Tgif  (bitmap  graphics),  -Tdia
       (GTK+ based diagrams), -Timap (imagemap files for httpd servers for each node or edge that
       has a non‐null "href" attribute.), -Tcmapx (client‐side  imagemap  for  use  in  html  and
       xhtml).   Additional  less  common  or more special‐purpose output formats can be found at
       http://www.graphviz.org/cvs/doc/info/output.html.)

       Alternative plugins providing support for a given output format  can  be  found  from  the
       error  message  resulting from appending a ':' to the format. e.g. -Tpng: The first plugin
       listed is always the default.

GRAPH FILE LANGUAGE

       Here is a synopsis of the graph file language,  normally  using  the  extension  .gv,  for
       graphs:

       [strict] (graph|digraph) name { statement‐list }
       Is the top level graph. If the graph is strict then multiple edges are not allowed between
       the same pairs of nodes.  If it is a directed graph, indicated by digraph, then the edgeop
       must  be  "->". If it is an undirected graph then the edgeop must be "--".  Statements may
       be:

       name=val;
       node [name=val];
       edge [name=val];
       Set default graph, node, or edge attribute name to  val.   Any  subgraph,  node,  or  edge
       appearing after this inherits the new default attributes.

       n0  [name0=val0,name1=val1,...];  Creates  node n0 (if it does not already exist) and sets
       its attributes according to the optional list.

       n0 edgeop n1 edgeop ... edgeop nn [name0=val0,name1=val1,...];
       Creates edges between nodes n0, n1, ..., nn and sets their  attributes  according  to  the
       optional list.  Creates nodes as necessary.

       [subgraph name] { statement‐list }
       Creates a subgraph.  Subgraphs may be used in place of n0, ..., nn in the above statements
       to create edges.  [subgraph name] is optional; if missing, the  subgraph  is  assigned  an
       internal name.

       Comments may be /*C‐like*/ or //C++‐like.

       Attribute  names  and  values  are  ordinary  (C‐style)  strings.   The following sections
       describe attributes that control graph layout.

GRAPH ATTRIBUTES

       size="x,y" sets bounding box of drawing in inches.

       page="x,y" sets the PostScript pagination unit.

       ratio=f sets the aspect ratio to f which may be a floating point number,  or  one  of  the
       keywords fill, compress, or auto.

       pagedir=[TBLR][TBLR] sets the major and minor order of pagination.

       rotate=90 sets landscape mode.  (orientation=land is backward compatible but obsolete.)

       center=n a non‐zero value centers the drawing on the page.

       layers="id:id:id:id"  is  a  sequence  of  layer  identifiers  for  overlay diagrams.  The
       PostScript array variable layercolorseq sets the assignment of colors to layers. The least
       index  is  1  and  each  element  must  be  a 3‐element array to be interpreted as a color
       coordinate.

       color=colorvalue sets foreground color (bgcolor for background).

       href="url" the default url for image map files; in PostScript files, the base URL for  all
       relative URLs, as recognized by Acrobat Distiller 3.0 and up.

       URL="url" ("URL" is a synonym for "href".)

       stylesheet="file.css"  includes  a  reference to a stylesheet in -Tsvg and -Tsvgz outputs.
       Ignored by other formats.

       splines. If set to true, edges are drawn as splines.  If set to polyline, edges are  drawn
       as  polylines.  If set to ortho, edges are drawn as orthogonal polylines.  In all of these
       cases, the nodes may not overlap.  If splines=false or splines=line, edges  are  drawn  as
       line segments.  The default is false.

NODE ATTRIBUTES

height=d or width=d sets minimum height or width. Adding fixedsize=true forces these to
be the actual size (text labels are ignored).

shape=record polygon epsf builtin_polygon
builtin_polygon is one of: plaintext ellipse oval circle egg triangle box diamond
trapezium parallelogram house hexagon octagon note tab box3d component. (Polygons are
defined or modified by the following node attributes: regular, peripheries, sides,
orientation, distortion and skew.) epsf uses the node's shapefile attribute as the path
name of an external EPSF file to be automatically loaded for the node shape.

label=text where text may include escaped newlines \n, \l, or \r for center, left, and
right justified lines. The string '\N' value will be replaced by the node name. The
string '\G' value will be replaced by the graph name. Record labels may contain recursive
box lists delimited by { | }. Port identifiers in labels are set off by angle brackets <
>. In the graph file, use colon (such as, node0:port28).

fontsize=n sets the label type size to n points.

fontname=name sets the label font family name.

color=colorvalue sets the outline color, and the default fill color if style=filled and
fillcolor is not specified.

fillcolor=colorvalue sets the fill color when style=filled. If not specified, the
fillcolor when style=filled defaults to be the same as the outline color.

fontcolor=colorvalue sets the label text color.

A colorvalue may be "h,s,v" (hue, saturation, brightness) floating point numbers between 0
and 1, or an X11 color name such as white black red green blue yellow magenta cyan or
burlywood, or a "#rrggbb" (red, green, blue, 2 hex characters each) value.

style=filled solid dashed dotted bold invis or any Postscript code.

layer=id or id:id or "all" sets the node's active layers. The empty string means no
layers (invisible).

The following attributes apply only to polygon shape nodes:

regular=n if n is non‐zero then the polygon is made regular, i.e. symmetric about the x
and y axis, otherwise the polygon takes on the aspect ratio of the label.
builtin_polygons that are not already regular are made regular by this attribute.
builtin_polygons that are already regular are not affected (i.e. they cannot be made
asymmetric).

peripheries=n sets the number of periphery lines drawn around the polygon. This value
supersedes the number of periphery lines of builtin_polygons.

sides=n sets the number of sides to the polygon. n<3 results in an ellipse. This
attribute is ignored by builtin_polygons.

orientation=f sets the orientation of the first apex of the polygon counterclockwise from
the vertical, in degrees. f may be a floating point number. The orientation of labels is
not affected by this attribute. This attribute is added to the initial orientation of
builtin_polygons.

distortion=f sets the amount of broadening of the top and narrowing of the bottom of the
polygon (relative to its orientation). Floating point values between -1 and +1 are
suggested. This attribute is ignored by builtin_polygons.

skew=f sets the amount of right‐displacement of the top and left‐displacement of the
bottom of the polygon (relative to its orientation). Floating point values between -1 and
+1 are suggested. This attribute is ignored by builtin_polygons.

href="url" sets the url for the node in imagemap, PostScript and SVG files. The
substrings '\N' and '\G' are substituted in the same manner as for the node label
attribute. Additionally the substring '\L' is substituted with the node label string.

URL="url" ("URL" is a synonym for "href".)

target="target" is a target string for client‐side imagemaps and SVG, effective when nodes
have a URL. The target string is used to determine which window of the browser is used
for the URL. Setting it to "_graphviz" will open a new window if it doesn't already
exist, or reuse it if it does. If the target string is empty, the default, then no target
attribute is included in the output. The substrings '\N' and '\G' are substituted in the
same manner as for the node label attribute. Additionally the substring '\L' is
substituted with the node label string.

tooltip="tooltip" is a tooltip string for client‐side imagemaps and SVG, effective when
nodes have a URL. The tooltip string defaults to be the same as the label string, but
this attribute permits nodes without labels to still have tooltips thus permitting denser
graphs. The substrings '\N' and '\G' are substituted in the same manner as for the node
label attribute. Additionally the substring '\L' is substituted with the node label
string.

EDGE ATTRIBUTES

label=text where text may include escaped newlines \n, \l, or \r for centered, left, or
right justified lines. If the substring '\T' is found in a label it will be replaced by
the tail_node name. If the substring '\H' is found in a label it will be replaced by the
head_node name. If the substring '\E' value is found in a label it will be replaced by:
tail_node_name->head_node_name If the substring '\G' is found in a label it will be
replaced by the graph name. or by: tail_node_name--head_node_name for undirected graphs.

fontsize=n sets the label type size to n points.

fontname=name sets the label font family name.

fontcolor=colorvalue sets the label text color.

style=solid dashed dotted bold invis

color=colorvalue sets the line color for edges.

color=colorvaluelist a ':' separated list of colorvalue creates parallel edges, one edge
for each color.

dir=forward back both none controls arrow direction.

tailclip,headclip=false disables endpoint shape clipping.

href="url" sets the url for the node in imagemap, PostScript and SVG files. The
substrings '\T', '\H', '\E' and '\G' are substituted in the same manner as for the edge
label attribute. Additionally the substring '\L' is substituted with the edge label
string.

URL="url" ("URL" is a synonym for "href".)

target="target" is a target string for client‐side imagemaps and SVG, effective when edges
have a URL. If the target string is empty, the default, then no target attribute is
included in the output. The substrings '\T', '\H', '\E' and '\G' are substituted in the
same manner as for the edge label attribute. Additionally the substring '\L' is
substituted with the edge label string.

tooltip="tooltip" is a tooltip string for client‐side imagemaps effective when edges have
a URL. The tooltip string defaults to be the same as the edge label string. The
substrings '\T', '\H', '\E' and '\G' are substituted in the same manner as for the edge
label attribute. Additionally the substring '\L' is substituted with the edge label
string.

arrowhead,arrowtail=none, normal, inv, dot, odot, invdot, invodot, tee, empty, invempty,
open, halfopen, diamond, odiamond, box, obox, crow.

arrowsize (norm_length=10,norm_width=5, inv_length=6,inv_width=7,dot_radius=2)

headlabel,taillabel=string for port labels. labelfontcolor,labelfontname,labelfontsize
for head and tail labels. The substrings '\T', '\H', '\E' and '\G' are substituted in the
same manner as for the edge label attribute. Additionally the substring '\L' is
substituted with the edge label string.

headhref="url" sets the url for the head port in imagemap, PostScript and SVG files. The
substrings '\T', '\H', '\E' and '\G' are substituted in the same manner as for the edge
label attribute. Additionally the substring '\L' is substituted with the edge label
string.

headURL="url" ("headURL" is a synonym for "headhref".)

headtarget="headtarget" is a target string for client‐side imagemaps and SVG, effective
when edge heads have a URL. The headtarget string is used to determine which window of
the browser is used for the URL. If the headtarget string is empty, the default, then
headtarget defaults to the same value as target for the edge. The substrings '\T', '\H',
'\E' and '\G' are substituted in the same manner as for the edge label attribute.
Additionally the substring '\L' is substituted with the edge label string.

headtooltip="tooltip" is a tooltip string for client‐side imagemaps effective when head
ports have a URL. The tooltip string defaults to be the same as the headlabel string.
The substrings '\T', '\H', and '\E' are substituted in the same manner as for the edge
label attribute. Additionally the substring '\L' is substituted with the edge label
string.

tailhref="url" sets the url for the tail port in imagemap, PostScript and SVG files. The
substrings '\T', '\H', '\E' and '\G' are substituted in the same manner as for the edge
label attribute. Additionally the substring '\L' is substituted with the edge label
string.

tailURL="url" ("tailURL" is a synonym for "tailhref".)

tailtarget="tailtarget" is a target string for client‐side imagemaps and SVG, effective
when edge tails have a URL. The tailtarget string is used to determine which window of
the browser is used for the URL. If the tailtarget string is empty, the default, then
tailtarget defaults to the same value as target for the edge. The substrings '\T', '\H',
'\E' and '\G' are substituted in the same manner as for the edge label attribute.
Additionally the substring '\L' is substituted with the edge label string.

tailtooltip="tooltip" is a tooltip string for client‐side imagemaps effective when tail
ports have a URL. The tooltip string defaults to be the same as the taillabel string.
The substrings '\T', '\H', '\E' and '\G' are substituted in the same manner as for the
edge label attribute. Additionally the substring '\L' is substituted with the edge label
string.

labeldistance and port_label_distance set distance; also labelangle (in degrees CCW)

decorate draws line from edge to label.

samehead,sametail aim edges having the same value to the same port, using the average
landing point.

layer=id or id:id or "all" sets the edge's active layers. The empty string means no
layers (invisible).

(neato‐specific attributes)
w=f sets the weight (spring constant) of an edge to the given floating point value. The
default is 1.0; greater values make the edge tend more toward its optimal length.

len=f sets the optimal length of an edge. The default is 1.0.

COMMAND LINE OPTIONS

       -G sets a default graph attribute.
       -N sets a default node attribute.
       -E sets a default edge attribute.  Example: -Gsize="7,8" -Nshape=box -Efontsize=8

       -lfile  loads  custom  PostScript  library  files.   Usually these define custom shapes or
       styles.  If -l is given by itself, the standard library is omitted.

       -Tlang sets the output language as described above.

       -O automatically generate output filenames based on the input filename and the -T format.

       -v (verbose) prints various information useful for debugging.

       -V (version) prints version information and exits.

       -? prints the usage and exits.

BUGS

       At present, patchwork ignores edges, and supplies no visual  clues  to  indicate  nesting.
       Such  clues might consist of nested boxes or thicker rectangular outlines. In addition, it
       would be good if some cluster label could be displayed.

       Patchwork has no mechanism for fitting labels within the supplied box.
