Red: categories. Grey: plugins
Here is the first graph:

3 bottom largest red nodes, from left to right: Desktop-only plugins, Uncategorized plugins, Mobile-compatible plugins
Somehow the 🗂️ 02.01 Plugins by Category note still sneaks in. I have no idea why. But deleting it doesn’t change the layout much.
Seeing that Desktop-only plugins and Mobile-compatible plugins are categories about platforms, not features, I delete them too. Here is the second graph:

And if we delete the Uncategorized plugins as well, then we have this graph:

The largest node now is Third-Party Integration Plugins, and the next is Plugins for Editing Notes.
It is possible to apply more graph theory to analyze this, but as the data is not complete I’m not sure what meaningful thing we can get from that analysis.
