        socnetv - Visualize and analyze social networks

SYNOPSIS

       socnetv < file.net >

       socnetv -V | --version

       socnetv -h | --help

DESCRIPTION

       Social  Networks  Visualiser  (SocNetV) is a cross-platform, user-friendly application for
       the analysis and visualization of Social Networks.

       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, UCINET, 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,
       PageRank, etc.

       Various  layout  algorithms  (i.e.  Spring-embedder,  radial and layered according to node
       centralization) are supported for meaningful visualizations of your networks. Furthermore,
       random networks (Erdos-Renyi, Watts-Strogatz, ring lattice, etc) can be created with a few
       clicks.

       SocNetV also offers a built-in web crawler, allowing you to automatically create  networks
       from all links found in a given initial URL.

       SocNetV  is  being  developed in C++ with the Qt5 GUI development toolkit. Qt5 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). The default file format is GraphML.

       You can load GraphML files by clicking on menu File > Load. To load other network formats,
       use the menu File -> Import.

       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 on by default. This slows down the application when the network  has  many
       nodes and edges. You can disable antialiasing by pressing F8 .
