Pre-CRAN waffle update - isotype pictograms
It seems Ruben C. Arslan had the waffle idea about the same time I did. Apart from some extra spiffy XKCD-like styling, one other thing his waffling routines allowed for was using FontAwesome icons. When you use an icon vs a block, you are…
Fixing Colors & Proportions in Jerusalem Post Election Graphics
Vis expert Naomi Robbins did an excellent critique of the graphics that went along with an article on Israeli election in the Jerusalem…
Making waffle charts in R (with the new 'waffle' package)
My disdain for pie charts is fairly well-known, but I do concede that there are times one needs to communicate parts of a whole graphically verses using just words or a table. When that need arises, I'm partial to "waffle charts" or…
Simple Lower US 48 Albers Maps & Local (no-API) City/State Geocoding in R
I've been seeing an uptick in static US "lower 48" maps with "meh" projections this year, possibly caused by a flood of new folks resolving to learn R but using pretty old documentation or tutorials. I've also been seeing an uptick in…
Streamgraph package now supports continuous x axis scale

NASA GISS’s Annual Global Temperature Anomaly Trends (dplyr/ggplot version)
D Kelly O’Day did a great post on charting NASA’s Goddard Institute for Space Studies (GISS) temperature anomaly data, but it sticks with base R for data munging & plotting. While there's absolutely nothing wrong with base R operations, I…
Power Outage Impact Choropleths In 5 Steps in R (featuring rvest & RStudio "Projects")
I and @awpiii were trading news about the power outages in Maine & New Hampshire last night and he tweeted the link to the @PSNH Outage Map. As if the Bing Maps tiles weren't bad enough, the use of a categorical color scale instead of a…
Visualizing Historical & Most-likely First Snowfall Dates for U.S. Regions
The impending arrival of the first real snowfall of the year in my part of Maine got me curious about what the most likely "first snow" dates are for my region. The U.S. Historical Climatology Network (USHCN) maintains historical daily…
