This is a super-interesting question. I don't think it is quite the answer to your question, but I have seen combined heatmaps/dendrograms that feel like a possibility for this? Maybe the heatmap deals with activity between nodes and the dendrogram handles the community cluster relationships? I see them often in bioinformatics Ex: https://en.wikipedia.org/wiki/Dendrogram#/media/File:Heatmap_RNAseqV2_1.png https://en.wikipedia.org/wiki/Dendrogram#/media/File:Heatmap...
