DirectedGraphWebMapPlugin

Draw a directed map of a web, part of a web, or of the structure around a single topic

Introduction

This plugin extends the DirectedGraphPlugin and draws a map of a web, part of a web, or of the structure around a single topic.

Example: Main Web

This is a sample of a web drawn by DirectedGraphWebMapPlugin - the "Main" web in a default installation of TWiki.

As you will notice, most topics are clickable when touched by the mouse, through clientside areamaps. (Only Web* system topics are not linked).

Syntax Rules

  • Place %WEBMAP% somewhere on the page to display a map of the entire web.
  • %WEBMAP{web="web" excludesystem="1" lr="1"}%
    • optional web="web" gives a map of the given web. Default 'this web'.
    • optional excludesystem="1" ignore TWiki system topics (WebNotify and friends). Default OFF
    • optional lr="1" orient graph left to right. Default orient graph top to bottom
    • optional size="2,1" maximum size of graph in inches (92dpi). For i.e. a maximum of ~800x600 use "8.5,6.5"

  • Place %TOPICMAP% somewhere on the page to display links for the given topic, to a given radius.
  • %TOPICMAP{web="web" topic="topic" links="2" backlinks="1" excludesystem="1" lr="1"}%
    • optional web="web" gives a map of the given web. Default 'this web'.
    • optional topic="topic" gives a map of the given topic. Default 'this topic'.
    • optional links="number" set the length of chain linking FROM the given topic. If not given, then take LINKS plugin setting, then 2.
    • optional backlinks="number" set the length of chain linking TO the given topic. If not given then take links then BACKLINKS plugin setting, then LINKS plugin setting, then 1.
