Good visual presentation should be evocative, as is this portion of a map “Romantic and Sexual Relations” at an unnamed high school, as reported by the research office at Ohio State University. Note that 63 pairs were unconnected to anybody else, and this info was self-reported. I’m just sayin’.
I know of at least one of these maps that was drawn for a well known field station. By the members of that field station. Nodes and links indeed.
