Introduce more visual navigations

E.g. this is a good start, but one clickable visualisation would be better.

This would also be good for clusters.

An external example: https://igor-biodgps.github.io/ARIADNE/graph/graph.html

Start by reviewing the FORRT website and the two linked visualization examples to understand the requested navigation style. Clarify which pages and cluster views are in scope, which existing entry points they should replace or extend, and what a clickable visualization must support before estimating completion.
