The data was pulled from ffnet over the course of several months and is probably outdated.
Data sources are the Toaru Majutsu No Index and the A Certain Scientific Railgun categories on ffnet.
Pairings with 3 or more members will be counted individually for each 2-member combination.
Note: The categories use partially different character names. Unfortunately, this wasn't noticed until these graphs were generated.
Generated using python3, ff2zim and the Chord library.
