The Periodic Box of Chocolates
By Henry Woodbury
People seem to forget that the periodic table is a table because it reads in two dimensions. Read it left to right and atomic weight increases. Read it top to bottom and you find elements with similar properties — for example, the alkali metals in group 1 or the noble gases in group 18. The gaps in periods 1, 2, and 3 represent physical realities about the electron configuration of those lighter elements (see this Periodic Table by Chemicool).
Most attempts to fit other data sets to the periodic table result in strange confections.
This Periodic Table of Visualization Methods is a prime example. A simple categorized list is puddled into the matrix of Dmitri Mendeleev’s table and shoved around to fit. There are exactly six “compound visualizations.” How serendipitous. The really interesting data — the examples of the methods — are hidden under reductive two-letter acronyms, making comparison impossible even when you do find something interesting.
If the categories are meaningful and not just quantified to fit the table, the next step is to abandon the presentation method that doesn’t work and come up with one that does.
