This was a tool I built to check if there was anything interesting in the relationship of topics to chapter and excitement rating. Basically, it shows that some topics are jointly assigned to chapters that are both dull and exciting, so no direct relationship, I think! You can see some thematic relationships over novel, both local and long-distance, though. See the talk and blog post by me (Lynn Cherny).
Blocks encode chapter "excitement" score (grey=dull to red=exciting) Arcs show shared topic matches.
