WebDot Home Page

WebDot is a CGI program that converts a graph description from a .dot file into an image that can be included on a web page. (As distributed, "Server 1" and "Server 2" are constrained to be the same host. If anyone wants to run a public WebDot server they can easily relax this constraint.)

WebDot is written in Tcl using the Tcldot package from graphviz-tcl.

Where can I get it?

The latest version of WebDot is available from: http://www.graphviz.org/

What does it need to run?

WebDot requires: graphviz-tcl and a web server (an httpd) such as Apache. WebDot has been developed and tested primarily on Fedora systems.

For viewing svg or svgz files you will need an svg-capable browser such as W3C Amaya. All modern browsers have svg support built in. You can learn more about browser compatibility here.
For viewing pdf files you will need a pdf plugin such as:  get pdf reader

Demos?

The demo page lists all of the demo graphs currently distributed with the graphviz package, with links to neato or dot layouts, in png, ps, pdf or svgz output formats. Other formats are available from the png result page.

Warnings

It's difficult to find a TCL plugin that works any more, so the last tutorial page probably won't load for you.
