Graphviz is Open Source graph-visualization software. Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. It has important applications in networking, bioinformatics, software engineering, database and web design, machine learning, and in visual interfaces for other technical domains.

Graphviz is quite a complex program despite the GUI although the developers assure that the engine behind it - a simple file format known as DOT - intelligently connects nodes to other nodes. A sophisticated layout routine then renders it into many different output formats including SGI, Photoshop, Windows BMP, JPEG, Macintosh PICT, PNG, MacPaint, TIFF, Targa, JPEG 2000 and Quicktime Image. You can preview graphs and if you're struggling with a setting, a 'Tooltips' tool automatically assists you. Graphviz is purely for those that know what they're doing with DOT files and need to plot complex graphs.
