graphics/graphviz - Graph Visualization
Integrated with J, a popular graph drawing visualization library.
Includes user interface Graph View and a utility to visualize
sequential machines (finite automata) in testsm folder.
See doc folder and help.html in installation for furter details.
See also companion cluster analysis Addons/stats/dendrite
Based on Graphviz from http://www.graphviz.org/
Installation
- Install using Package Manager to install ~addons/graphics/graphviz.

Graph View
First-time use:
load 'graphics/graphviz'
Subsequent calls:
graphview '' NB. show empty view
graphview 'digraph G { a->b }',LF NB. show from graph def
graphview '~addons/graphics/graphviz/testsm/cut.dot' NB. show graph file
User interface: simple and intuitive.
Use menu and help and links for further assistance.
All output uses Qd webview as the display engine.
Examples:
For Windows, open ~addons/graphics/graphviz/graphs folder for numerous examples.
For Ubuntu: /usr/share/doc/graphviz/examples/graphs
For Centos: /usr/share/graphviz/graphs
Sequential Machine View
Sequential machine definition graph visualizer. See 
.
Load:
load 'graphics/graphviz/smgraph'
Use, where optional states and inputs are lists of labels, s is state table
and r is initial state number:
[states;inputs] smview s[;r]
Example of dyad ;: "Words" using ~addons/graphics/graphviz/testsm/jdic.ijs

See ~addons/graphics/graphviz/testsm/*.ijs for more examples.
Extensibility
Using ~addons/graphics/graphviz/smgraph.ijs as a model, it is possible to create custom graph visualizers for various applications.
