Adding edge events would add a lot, because we're already visualizing 30040/30041 with a star topology. An edge event pointing to a 30040 event means you're connecting to notes that have already been classified together, meaning you can collapse a bunch of nodes into a single one. You can even make the edge events point to tags, or pubkeys which actually would be a fuzzy graph structure, because you don't know how many connections you'll have. 👀
