How xkcd Does Maps

Randall Munroe, author of the xkcd web comic, posts a surprising amount of map-related content, which I invariably end up linking to here. With some exceptions, they fall into one of two categories, each of which has a recent example.

The first category is a hand-drawn infographic map showing, in earnest, some interesting or surprising information. See, for example, this map showing the most observed animal or plant in each U.S. state:

Randall Munroe, “iNaturalist Animals and Plants,” xkcd, 21 Jul 2025.

Other maps of this ilk include drainage basins, lesser-known towns sharing a famous place name, least informative Google Trends maps, and maps of the 2016, 2018 (challengers) and 2020 elections.

The second category is where Randall chooses the path of violence, with maps clearly designed by Black Hat Guy to hurt our brains. These include a series of maps that mangle U.S. state borders (1, 2, 3). But the most insidious are his Bad Maps Projections series, the most recent of which projects continents onto their own globes:

Randall Munroe, “Bad Map Projection: Interrupted Spheres,” xkcd, 30 Jul 2025.

Thing is, this one isn’t as brain-curdling, because similar globes—globes that depict a portion of the world on an entire sphere—exist in the real world.

A Globe Safety Tip from xkcd

Randall Munroe, “Globe Safety,” xkcd, 7 May 2025.

In Wednesday’s xkcd comic, Replogle has apparently been taken over by mad scientists. I’m having a hard time resisting the urge to explain the joke (I doubt many of my readers are physicists, but then I’m not one either). But in a weird Einsteinian way Randall is doing with globes and mass what Carroll, Borges and Eco did with maps and space: assume a 1:1 ratio between the map and the mapped.

xkcd: ‘Every Eclipse Path Map’

Looks like we’re not quite done with eclipse maps, especially the whimsical sort, and it’s not at all invalid for xckd to have (what is probably going to be) the last word on the subject (at least for a while), with this fictional map showing the fictional path of a fictional eclipse over a fictional landscape, with rueful descriptions of fictional places where trying to see the fictional eclipse will come to a bad end for the fictional observers. (And you thought it was bad you got clouds.)

xkcd on Greenland’s Size

xkcd: Greenland Size (25 Mar 2024)
Randall Munroe, “Greenland Size”, xkcd, 25 March 2024.

The 25 March 2024 xkcd honours Greenland’s place as a measure of cartographic distortion. It’s also, unexpectedly, a riff on the idea of the 1:1 scale map (cf. Borges), especially if you consult the comic’s alt text: “The Mercator projection drastically distorts the size of almost every area of land except a small ring around the North and South Poles.”

‘Whoops, Made All Longitudes Positive’

xkcd:Bad Map Projection: ABS(Longitude)
Randall Munroe, “Bad Map Projection: ABS(Longitude),” xkcd, 26 Jul 2023.

The latest in Randall Munroe’s Bad Map Projection series on xkcd is perhaps his most evil yet: it turns all longitudes positive—i.e., it turns west longitude into east longitude, putting Quebec somewhere in Kazakhstan and the Panama Canal off Sri Lanka.

xkcd: The Goode Homolosine to the Rescue!

Randall Munroe, “Sea Chase,” xkcd, 4 Feb 2022.

Randall Munroe’s map projection humour is increasingly on point, as last Friday’s xkcd demonstrates. (The mouseover text is even better: “There are two rules on this ship: Never gaze back into the projection abyss, and never touch the red button labeled DYMAXION.”)
