I enjoyed the recent anime series Mawaru Penguindrum. This is a map of the inter-character relationships, as best as I could make them out. Spoilers, naturally.

I did my best to duplicate the subway-map aesthetic that appeared in the series. The series (and the actual Tokyo Metro) uses the font Frutiger for its roman-character signage. Sadly, I don't have Frutiger but Futura seemed closer to it than Helvetica.

Corrections and suggestions welcome.
