Hey! I know there's already a graph view plug out there, but it didn't quite match what I was looking for, so I built my own. I figured I'd share it in case it's useful to others as well.
Atlas shows your pages and wikilink connections as an interactive force-directed graph in the right panel.
Orphan pages: there's a toolbar toggle to show/hide unlinked pages. They get their own color, so they're easy to spot.
Toolbar: it's there, built to take more buttons as features come.
Still on the list:
Coloring non-existing pages differently - good call, would make it obvious where you've linked to something that doesn't exist yet.
show/hide tags, documents
live text filter
Script-generated links: links produced dynamically by Space Lua templates aren't picked up by the graph yet, e.g. ${string.format("[[Journal/%s|Today's Journal]]", os.date("%Y-%m-%d"))}.
