Color-Code time in the graph view

Introduction:
In general I do like the graph view to explore my Knowledge Base in a visual way! I think it’s really fun to see the connections between notes and the clusters the notes form around certain topics.
But I do think the graph view could be used for more - for example to discover old topics/notes in order to revisit them or prune (delete) them from my Knowledge Base!


Feature Request:
Add the ability to use color to visualize the creation-date, last-edited-date or last-viewed date of a note in the graph-view.
This way the Knowledge Graph can be used to intentionally revisit “older” areas!
This could be useful to stay in control of your Knowledge Base without “forgetting” old areas.

During the revisit the user can decide whether the information is still useful or if it can be deleted/archived to keep the Knowledge Base clean. Maybe the user also decides to update the old note by adding new insights, which have been gained in the meantime.
