Brinton's 1914 viz manual already banned 3D and chart junk
Willard C. Brinton's Graphic Methods for Presenting Facts (1914) and its 1939 successor read like modern style guides. Bar charts beat pies, 3D graphics are called "much worse than figures alone," the don't-start-at-zero trick gets debunked, and a heatmap already raised millions for US schools. Every dashboard fight you're having was settled a century ago.
