Electing the House of Representatives, 1840-2016

There’s a lot of stuff relevant to our interests on the website of the University of Richmond’s Digital Scholarship Lab, and it’s hard to know what to begin with. One of the more recent projects, which CityLab saw fit to link to yesterday, is an interactive map showing elections to the U.S. House of Representatives from 1840 to 2016. It’s the kind of project that the user can get very, very lost in. In addition to the usual map of U.S. congressional districts, the site can also visualize the districts as a dot map to minimize the empty-land-doesn’t-vote problem (they call it a cartogram: it isn’t). There’s also a timeline showing the overall results over time at a glance; selecting a district gives shows how the district voted in past contests as a line graph. In other words: quite a lot of data, economically presented.
