Maps & Visualizations gallery

Here’s an incomplete gallery with links to some data visualizations and maps I’ve made: many are interactive, so you’ll need to click through through for the full experience.

Archetypal Plot Structures

Law_& Order

Using topic modeling and my database of 80,000 film and TV captions, I look at the typical plot structures for about 150 common TV shows. (This one is not an interactive, at least not yet: but it was all built entirely in the interactive bookworm browser.)

Corrected Subway Maps

This is a set of transit maps deformed to fit onto the Internet map-tile view of the cities (Boston, New York, Washington) they depict; it explores the tension between two different ways of representing the same urban spaces. Made using QGIS, Leaflet, and some command-line GDAL tools with maps and data from the transit authorities and tiles from Open Street Map.

Baseball leaderboard cherrypicker

This lets you navigate through thousands of statements of the form “Jack Morris led the majors in wins in the 1980s” and decide which ones are important. It speaks to a larger collection of questions about how quantitative claims like those made in baseball (or in the earlier version of the same idea I made about college degrees) often take more context than the basic statements allow. Made using R and D3 from data in the Lahman database and from baseballprospectus.com.

College Majors and Degrees

Students and professors alike often don’t know what careers a particular major leads into; using census data from the American Community Survey, this Sankey diagram lets you see many of the different paths that college graduates take. It’s a pretty basic 2-column sankey layout, but has two nice features: color coded lines to show relative significance of flows, and a click-to-zoom interface that lets you look at one particular field.

Changing College Majors

A practical visualization of department of education data about what college students major in: it’s highly interactive, and lets you choose which majors, you want to look at, which metrics of quantity, and which colleges you want to include. Also includes a few example story walkthroughs. Made using D3 with data from the NSF (and originally department of education).

Ghost shipping paths

Probably the most widely-circulated image I’ve made is this chart that shows the paths of ships taken from the US Maury collection of the government’s database of ship’s paths. I made it to illustrate how rich metadata alone can be as a source for historical research: it’s also just an interesting way to see the continents through large-scale patterns of behavior. Several people asked for higher-resolution versions; I recreated a couple charts on the same concept are here.

Shipping animations

Using a similar dataset, I also made a set of movies showing ocean sailing in motion using ggplot2 and ffmpeg. Here’s one of them; the rest are available on my YouTube channel, and I wrote quite a bit about them on my blog.

 Migrations in 1880

An experimental interactive map (experimental here meaning “too long a load time” to show interstate migrations in the 1880 census.) This can be used to explore some interesting stories about regional connections in the period after the end of slavery (for example, by looking at the relative sources of migration in different western counties to see which eastern states their residents came from.) Graphically, I found it interesting to have two maps (one of counties and one of states), which switch roles as legend or content depending on what direction of migration you want to look at.
