Making Static/Interactive Voronoi Map Layers In ggplot/leaflet
Despite having shown various ways to overcome D3 cartographic envy , there are always more examples that can cause the green monster to rear it's ugly…
A Path Towards Easier Map Projection Machinations with ggplot2
The $DAYJOB doesn't afford much opportunity to work with cartographic datasets, but I really like maps and tinker with shapefiles and geo-data when I can, plus answer a ton of geo-questions on StackOverflow. R makes it easy—one might even…
Using the new 'viridis' colormap in R (thanks to Simon Garnier)
Nathaniel Smith and Stéfan van der Walt presented a new colormap (for Python) at SciPy 2015 called viridis…
Faceted "World Population by Income" Choropleths in ggplot
Poynter did a nice interactive piece on world population by income (i.e. "How Many Live on How Much, and Where" ). I'm always on the lookout for optimized shapefiles and clean data (I'm teaching a data science certificate program starting…
metricsgraphics 0.8.5 is now on CRAN!
I'm super-pleased to announce that the Benevolent CRAN Overlords accepted the metricsgraphics package into CRAN over the weekend. Now, you no longer need to rely on github/devtools to use MetricsGraphics.js charts from your R scripts. If…
Animated US Hexbin Map of the Avian Flu Outbreak
The recent announcement of the start of egg rationing in the U.S. made me curious enough about the avian flu outbreak to try to dig into the numbers a bit. I finally stumbled upon a USDA site that had an embedded HTML table of flock…
A quick, incomplete comparison of ggplot2 & rbokeh plotting idioms
I set aside a small bit of time to give rbokeh a try and figured I'd share a small bit of code that shows how to make the "same" chart in both ggplot2 and…
U.S. Drought Monitoring With Hexbin State Maps in R
On the news, today, of the early stages of drought hitting the U.S. northeast states I decided to springboard off of yesterday's post and show a more practical use of hexbin state maps than the built-in (and still purpose unknown to me)…
GeoJSON Hexagonal "Statebins" in R
There's been lots of buzz about "statebin" maps of late. A recent tweet by @andrewxhill referencing work by @dannydb pointed to a nice shapefile ( alternate link ) that ends up being a really great way to handle statebin maps (and I feel…
A look at airline crashes in R with googlesheets, dplyr & ggplot2
Over on The DO Loop, @RickWicklin does a nice job visualizing the causes of airline crashes in SAS using a mosaic plot. More often than not, I find mosaic plots can be a bit difficult to grok, but Rick's use was spot on and I believe it…
