This is my favorite blockchain visualization. Imagine something like this for following/followers, or even posts/comments to show the provenance record.

This is something that is very hard to achieve purely client side, since it is data and cpu intensive. About the visualization: graphs are cool, but they should really offer a useful perspective, and I don't see much possible innovations here; a graph of names/pictures is quite useless without any segmentation about interests and activity patterns. A WoT score like Coracle.social could probably be sufficient to highlight contacts that have a good trust level. @hodlbod can you share your experience about implementing the WoT?
