Thought this was going to be about CSV files with cryptic column names. Any advice on codebook formats for table and column level metadata?

Finding a clever name for a graph is at least half the battle for success.

At least I found a few JMP bugs in the process — my typical Monday starts with filing or fixing issues I find over the week-end.😀

Same-sex marriage 7/7: A couple left-over tile grid maps. I noticed the number of years, 21, is a triangular number, so triangles!. The tapered bars were to help separate the states and make the more recent years more important.

Same-sex marriage 5/7: Bump chart with status coloring. The coloring serves as a nation-level bar chart for getting the big picture. Took me forever to break ties in a way that reduces unnecessary line crossings.

Same-sex marriage 4/7 Tile grid map of calendar-style heat maps, omitting the last year where every state was the same anyway to use a nice 4x5 layout.

Same-sex marriage 3/7: Small multiples: choropleth maps over time. Easier to see the few regional trends, but harder to see individual State histories.

Same-sex marriage 2/7: Perhaps the simplest view, a heat map table, is best. Here I ordered states by the average status, but alphabetic would be better for look-up.

Spent too much time this week-end playing with data for r/dataisbeautiful February Battle. Same-sex marriage legal status: 4 levels over 50 states and 21 years. Small data but still many choices: emphasize time, or geography, or rank, or …. 1/7

Yeah, the spatial pattern--starting sooner in the south--is too subtle for this form.

I've been trying lightly filled boxes (without the gradient). Seems to overlay with markers better than error bars and matches with filled regression confidence intervals.
