Describe the solution you'd like

I would like a graph view like the one in obsidian.

A graph view is a graph that shows which page is connected to which tags.

Additional context

I don't really know if this is realistic and if its not, then just close this issue.

Idea(s) for implementation:

1. An extra tab named graph.
2. Something like; graph-view: yes graph-link: yes

it is a great feature that isnt just a cool element but serves a very important function ie discoverability. it is very reasonable and attractive method of showing connection between pages and building a knowledge graph on the website
