TW5-Graph is a framework to integrate TiddlyWiki with existing graphing and visualization engines (such as Vis-Network). The plugin allows for easy and sophisticated graphs to represent your tiddlers, or whatever else you want.

It is the spiritual successor to TiddlyMap.

With TW5-Graph you can:

• Quickly create and edit graphs through a simple point-and-click GUI
• Use wikitext widgets to create customized graphs and template to exactly match your needs
• Easily create dynamic graphs to represent changing state or individual tiddlers

There's loads TW5-Graph can do for you. Check out its demo website here.
