What is "tiddlymap"

TiddlyMap is a graph drawing plugin developed for the single-page application TiddlyWiki. It allows you to connect your wiki topics (so called tiddlers) in order to display the resulting networks as clickable graphs. These graphs may be embedded in the overall wiki content at any point. TiddlyMap is not only capable of displaying explicitly created connections, but has the ability to automatically track and visualize existing relationships between articles such as links, backlinks and tag relationships. The browser based visualization library Vis.js is used as rendering engine.
