NAME

        socnetv - Visualize and analyze social networks

SYNOPSIS

       socnetv < file.net >

       socnetv -V | --version

       socnetv -h | --help

DESCRIPTION

       Social  Networks  Visualiser  (SocNetV)  is  a  flexible and user-friendly tool for Social
       Networks Analysis and Visualisation. It lets you construct networks (mathematical  graphs)
       with  a  few  clicks  on  a  virtual canvas or load networks of various formats (GraphViz,
       GraphML, Adjacency, Pajek, etc) and modify them to suit your needs.

       The application can compute basic  network  properties,  such  as  density,  diameter  and
       distances (shortest path lengths), as well as more advanced structural statistics, such as
       node and network centralities (i.e. closeness, betweeness, graph), clustering coefficient,
       etc.

       It  supports  various  layout  algorithms  (i.e.  Spring-embedder,  circular and in levels
       according to various centrality indeces) for meaningful visualisations of social networks.
       Furthermore,  random  networks  (Erdos-Renyi,  Watts-Strogatz,  ring  lattice, etc) can be
       created with a few clicks.

       SocNetV is being developed in C++ with the Qt GUI development  toolkit.  Qt  is  the  only
       dependency.

OPTIONS

       --version | -V
              Displays the version of the program.

       --help | -H
              Displays a short help message.

       file.net
              The name of the file you want to open.

USAGE

       SocNetV  has  a  simple  Graphical  User  Interface (GUI). The biggest (right) part of the
       window is occupied by a virtual "canvas" where network nodes and edges appear. To the left
       of  it,  there  is  a dock with 4 buttons (add/remove node, add/remove link) and some LCDs
       which display statistics. On the top of the window,  you  will  find  the  menu  with  all
       commands and options, and at the bottom there is a status bar, where messages appear.

       To  create  a  new  node,  you  can  double-click on the canvas or click on the "add node"
       button.

       To create a new link, you can middle-click on the source node and then on the target node.
       Alternatively, you can click on the "add link" button from the dock.

       You  move  a  node  by  left-clicking  and  dragging it. When you right-click on a node, a
       context menu appears. From there you can remove the node, change its color, label, size as
       well  as  its  shape. SocNetV supports many kinds of node shapes, i.e rectangles, diamond,
       ellipse, circle, etc. A similar menu  appears when you right click on a link.

       Supported Formats

       SocNetV supports many network formats, i.e. GraphViz  (.dot),  GraphML  (.graphml),  Pajek
       (.net),  Adjacency  matrix  (.net, .txt). You can load these kinds of files by clicking on
       menu File > Load or by specifying them explicitly  at  the  command  line.   SocNetV  uses
       simple  inspection  routines to check the format of the given file. In most cases, it will
       load the file, no matter what the file extension is.

       Layout algorithms

       SocNetV also supports a variety of layout algorithms, such as spring-embedder (i.e. energy
       based)  and  centralities-based.  The  latter reposition all nodes in circles of different
       radiuses (i.e. more central nodes appear near the centre of the canvas) or  in  levels  of
       different height (more central nodes appear near to the top).

       You  can  apply layout algorithms from the menu Layout or by clicking on the checkboxes on
       the dock. Not all layouts appear on the dock, though.

KNOWN BUGS

       The network file parser is not  100%  trustworthy.  For  instance,  complicated  Pajek  or
       GraphML files can crash the application.

       Antialiasing  is  off  by  default  to  boost  the  speed of node movement. You can enable
       antialiasing by pressing F8.
