Playing with Marvel API data to d3 visualization(s).
Generally a playground of works in progress, but sharing regardless.
A visualization to show that Deadpool isn't in the Marvel Cinematic Universe, or Marvel film character co-occurrences (two characters showing up in the same film) clustered by their main series to distinguish the Marvel Cinematic Universe (Avengers), the Earth-10005 Universe (X-Men), and the Marvel TV Series on Netflix (The Defenders)
A visualization of the top 100 (by comic appearance) Marvel comic book character co-occurrences (two characters showing up in the same comic) across the history of Marvel Comics
A visualization of all Marvel comic book character co-occurrences (two characters showing up in the same comic) across the history of Marvel Comics
I've not shared the script used to pull data from Marvel's API - I'll leave that to you to do on your own. That said, to build these visualizations I did have to cache an extensive amount of data from Marvel Developer. That data will be updated regularly according to the Marvel Developer terms of use.
