It tries to address something that I find frustrating about election maps: Very few of them do a good job of showing where voters are. […] There are more Trump voters in California than Texas, more Biden voters in Texas than New York, more Trump voters in New York than Ohio, more Biden voters in Ohio than Massachusetts, more Trump voters in Massachusetts than Mississippi, and more Biden voters in Mississippi than Vermont.
The thing about this xkcd cartoon is that at first glance it’s entirely plausible: Randall has done violence to state boundaries while maintaining the rough overall shape of the lower 48. He’s snipped out seven states without anyone noticing if they don’t look too closely.
xkcd is back with another bad map projection: in this one, it’s all South Americas. The alt-text: “The projection does a good job preserving both distance and azimuth, at the cost of really exaggerating how many South Americas there are.”
By law, I am required to share every xkcd comic about maps. Today’s makes great fun of pop versus soda maps—the maps showing where in the U.S. carbonated beverages are referred to as pop versus where they’re referred to as soda. Randall takes things to their ludicrous extremes, as he is, by law, required to do.
The web comic xkcd has done maps before (and I’ve covered most of them) but Friday’s iteration was a departure all the same: an interactive map of the challengers in the 2018 U.S. midterm elections: the larger the candidate’s name, the more significant the office and the better their odds of winning. Remember, these are only the challengers: no incumbents are listed.
The maps that appear from time to time on xkcd are usually a lot more whimsical than the one Randall posted today: his somewhat belated “2016 Election Map” assigns one figure for every 250,000 votes for each of the 2016 presidential election candidates. As Randall says in the alt text,1 “I like the idea of cartograms (distorted population maps), but I feel like in practice they often end up being the worst of both worlds—not great for showing geography OR counting people. And on top of that, they have all the problems of a chloro… chorophl… chloropet… map with areas colored in.” This is an issue that election map cartographers regularly have to deal with, as many of my readers know well.
Randall Munroe is a bad man who is back with another bad map projection to make our eyes bleed. (If he does this often enough he’ll have enough for a book. Heaven forfend.) This one is, like his other maps, fiendishly subtle: it stretches and compresses countries to fit where their time zones ought to be, longitudinally speaking.
