I wonder what all the color codes and stuff mean. I'm guessing it has something to do with which media they appeared in.
You are right - in the cirlces is somewhat defining kanji from media name. I guessed that by recognizing EoSD, IN and HSiFS kanji in circles and character's appearances.
Pretty much every character has shown up in Books and Etc. though, so for example Clownpiece, you'd think she'd get a bit more than just the LolK mention since she's been a sort of focus in at least a few of the three fairies manga chapters.
Note to anyone who tries to take Hellbus' advice and just copy/paste notes from older versions of this image:
The text may be (nearly) identical, but the X/Y positions of the text on the image are not. You'd have to copy and paste the notes one at a time, rather than simply do them en masse all at once.

Doing them one at a time is what I was referring to. I wasn't aware of any other means of doing so.
