Map and Data Visualization Gallery
The tracks of vessels from the ICOADS database. 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 here
One point per person in the US for the 2010 and 2020 censuses, fully zoomable and interactive using WebGL and Deepscatter. Since this uses WebGL individual point rendering and quadtiled data, it can be far more responsive than raster-based maps you may have seen in 2010. Plus, if you zoom all the way in in some views it has little person glyphs!
This is less a data visualization than a primitive for making them. If you've never heard of the Hilbert Curve, there's nothing you'll care to see here. But Job van der Zwan and Martin Wattenberg have done interesting things with the under-appreciated H-Curve, and there's a lot more could be done. Plus it's fun to watch the animation.
The hard part of this is Philippe Riviere's extraordinary work creating something called the Voronoi Projection. I noticed, though, that enables what I call 'Data Driven Projections,' map representations of the world customized for any set of points. The one below shows the voyage of the Beagle in the 1830s, with Darwin; you can change the observable notebook at this link for any dataset you like.
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.)
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.
