11.0.0 Graph visualization tool for Windows

App for creating and visualizing complex graphs and networks with various layout options and customization capabilities.

Graphviz 11 is a freeware graph visualization app and image editor developed by John Ellson for Windows, it's feature-rich and user friendly.

The download has been tested by an editor here on a PC and a list of features has been compiled; see below.


Creates graphs in several formats including SVG for the web

Graphviz is open source graph visualization software. It has several main graph layout programs. It also has web and interactive graphical interfaces, and auxiliary tools, libraries, and language bindings

The Graphviz layout programs take descriptions of graphs in a simple text language, and make diagrams in several useful formats such as images and SVG for web pages, Postscript for inclusion in PDF or other documents; or display in an interactive graph browser. (Graphviz also supports GXL, an XML dialect.)

The Graphviz application has many useful features for concrete diagrams, such as options for colors, fonts, tabular node layouts, line styles, hyperlinks, and custom shapes.

In practice, graphs are usually generated from an external data sources, but they can also be created and edited manually, either as raw text files or within a graphical editor. (Graphviz was not intended to be a Visio replacement, so it is probably frustrating to try to use it that way.
