Graph view would benefit as a research / analytics tool with a few “simple” enhancements:
Add editable minimum and maximum values to node size and allow the selection of the metric for the calculation.
Offer a choice of linear / logarithmic / exponential node size growth to be able to spot differences more easily or smooth differences.
Similar requests for link thickness.
Check examples of node / link metrics: https://reference.wolframcloud.com/language/guide/GraphMeasures.html
I’m sure the development team is well aware of the possibilities here given the amazing work they delivered already.
Allow the selection of nodes and links colours based on metrics (based on tags is already a feature request).
Add filters to hide / show nodes and links below or above certain thresholds for the metrics.
Add a node text size parameter on the graph view. The current setting tends to generate very small fonts on my setup (modern Mac with external 4K monitor). For others it might be too large, or maybe perfect… but let us decide what we need, please.
On large and complex vaults this allows us to identify key notes, relevant paths and links. This information highlights what is important that we might be overlooking, what can be ignored (filtered) because it’s noise, what needs further research because it’s not strong enough (doesn’t have enough evidence references or citations, for example).
A couple of examples of what is possible on graph analysis:
