Over on The DO Loop, @RickWicklin does a nice job [visualizing the causes of airline crashes](http://blogs.sas.com/content/iml/2015/03/30/visualizing-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 shows the data pretty well, but I also… Continue reading

Fixing Colors & Proportions in Jerusalem Post Election Graphics
Vis expert Naomi Robbins did an excellent [critique](http://www.forbes.com/sites/naomirobbins/2015/03/19/color-problems-with-figures-from-the-jerusalem-post/) of the [graphics](http://www.jpost.com/Israel-Elections/Analysis-The-Israel-election-decided-by-one-vote-394229) that went along with an article on Israeli election in the Jerusalem Post. Non-uniform and color-blind-unfriendly categorical colors and disproportionate arc sizes are definitely three substantial issues in that series of visualizations. We can rectify all of them with two new packages of mine:… Continue reading
Making waffle charts in R (with the new ‘waffle’ package)
NOTE: The waffle package (sans JavaScript-y goodness) is up on CRAN so you can do an install.packages(“waffle”) and library(waffle) vs the devtools dance. 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…. Continue reading
Streamgraph package now supports continuous x axis scale
A post on [StackOverflow](http://stackoverflow.com/questions/28725604/streamgraphs-dataviz-in-r-wont-plot) asked about using a continuous variable for the x-axis (vs dates) in my [streamgraph package](http://github.com/hrbrmstr/streamgraph). While I provided a workaround for the question, it helped me bump up the priority for adding support for continuous x axis scales. With the [DBIR](http://www.verizonenterprise.com/DBIR/) halfway behind me now, I kicked out a new rev… Continue reading
New release (0.7) of metricsgraphics htmlwidget — grids & rollovers
I’ve updated my [metricsgraphics](https://github.com/hrbrmstr/metricsgraphics) package to version [0.7](https://github.com/hrbrmstr/metricsgraphics/releases/tag/v0.7). The core [MetricsGraphics](http://metricsgraphicsjs.org) JavaScript library has been updated to version 2.1.0 (from 1.1.0). Two blog-worthy features since releasing version 0.5 are `mjs_grid` (which is a `grid.arrange`-like equivalent for `metricsgraphics` plots and `mjs_add_rollover` which lets you add your own custom rollover text to the plots. ### The Grid… Continue reading
NASA GISS’s Annual Global Temperature Anomaly Trends (dplyr/ggplot version)
D Kelly O’Day did a [great post](https://chartsgraphs.wordpress.com/2015/01/16/nasa-gisss-annual-global-temperature-anomaly-trends/) 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 thought a modern take on the chart using `dplyr`, `magrittr` & `tidyr` for data manipulation… Continue reading
New R Package: metricsgraphics
Mozilla released the [MetricsGraphics.js library](http://metricsgraphicsjs.org/) back in November of 2014 ([gh repo](https://github.com/mozilla/metrics-graphics)) and was greeted with great fanfare. It’s primary focus is on crisp, clean layouts for interactive time-series data, but they have support for other chart types as well (though said support is far from comprehensive). I had been pondering building an R package… Continue reading
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](http://www.psnh.com/outage/). As if the Bing Maps tiles weren’t bad enough, the use of a categorical color scale instead of a sequential one[[1](http://earthobservatory.nasa.gov/blogs/elegantfigures/2011/05/20/qualitative-vs-sequential-color-scales/)] caused sufficient angst that I whipped up… Continue reading
