#Pournelle - perhaps most widely #famous for being a great science-fiction #author, frequently in collaboration with Larry #Niven and Stephen #Barnes - was a bit of a polymath. He invented the 2-axis scale now known as a "Pournelle chart" in his political science Ph. D. dissertation, in 1963.

See: https://en.wikipedia.org/wiki/Pournelle_chart

A 1-axis chart misrepresents views or policies so badly you end up with, for example, #communists, #socialists, and #liberals all close together. (edit: thinko)
