Pre-CRAN waffle update – isotype pictograms

March 26, 2015 | hrbrmstr

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 really making a basic version of ...

Fixing Colors & Proportions in Jerusalem Post Election Graphics

March 20, 2015 | hrbrmstr

Vis expert Naomi Robbins did an excellent critique of the graphics 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 ...

Making waffle charts in R (with the new ‘waffle’ package)

March 18, 2015 | hrbrmstr

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 “square pie charts”. @eagereyes did a great ...

Simple Lower US 48 Albers Maps & Local (no-API) City/State Geocoding in R

March 15, 2015 | hrbrmstr

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 folks needing to geocode US city/state ...

Streamgraph htmlwidget version 0.7 released (adds support for markers & annotations)

March 12, 2015 | hrbrmstr

In preparation for using some of our streamgraphs for production (PDF/print) graphics, I ended up having to hand-edit labels in on one of the graphics in an Adobe product. This bumped up the priority on adding annotation functions to the streamgraph package (you really don’t want to have ... [Read more...]

New R Package – ipapi (IP/Domain Geolocation)

March 9, 2015 | hrbrmstr

I noticed that the @rOpenSci folks had an interface to ip-api.com on their ToDo list so I whipped up a small R package to fill said gap. Their IP Geolocation API will take an IPv4, IPv6 or FQDN and kick back a ASN, lat/lon, address and more. The ... [Read more...]

Streamgraph package now supports continuous x axis scale

March 7, 2015 | hrbrmstr

A post on StackOverflow asked about using a continuous variable for the x-axis (vs dates) in my streamgraph package. 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 halfway behind me now, I ... [Read more...]

Introducing the streamgraph htmlwidget R Package

February 15, 2015 | hrbrmstr

We were looking for a different type of visualization for a project at work this past week and my thoughts immediately gravitated towards streamgraphs. The TLDR on streamgraphs is they they are generalized versions of stacked area graphs with free baselines across the x axis. They are somewhat controversial but ... [Read more...]

SweetheaRstats

February 12, 2015 | hrbrmstr

I felt compelled to dust off my 2013 Valentine’s Day #rstats post and make it all Shiny and new again. I used the same math from that post, but made the polygon a bit sharper and used ggplot2 for the plotting. To kick it up a bit, I decided to ... [Read more...]

A Step to the Right in R Assignments

February 4, 2015 | hrbrmstr

I received an out-of-band question on the use of %% in my CDC FluView post, and took the opportunity to address it in a broader, public fashion. Anyone using R knows that the two most common methods of assignment are the venerable (and sensible) left arrow [Read more...]

New release (0.7) of metricsgraphics htmlwidget — grids & rollovers

February 1, 2015 | hrbrmstr

I’ve updated my metricsgraphics package to version 0.7. The core MetricsGraphics 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 ...

NASA GISS’s Annual Global Temperature Anomaly Trends (dplyr/ggplot version)

January 18, 2015 | hrbrmstr

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 thought a modern take on the chart using ...

New R Package: cdcfluview — Retrieve Flu Data from CDC’s FluView Portal

January 10, 2015 | hrbrmstr

Towards the end of 2014 I had been tinkering with flu data from the CDC’s FluView portal since flu reports began to look like this season was going to go the way of 2009. While you can track the flu over at The Washington Post, I like to work with data ...

New R Package: metricsgraphics

January 8, 2015 | hrbrmstr

Mozilla released the MetricsGraphics.js library back in November of 2014 (gh repo) 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 ...

Making Static & Interactive Maps With ggvis (+ using ggvis maps w/shiny)

December 29, 2014 | hrbrmstr

Even though it’s still at version 0.4, the ggvis package has quite a bit of functionality and is highly useful for exploratory data analysis (EDA). I wanted to see how geographical visualizations would work under it, so I put together six examples that show how to use various features of ...

Power Outage Impact Choropleths In 5 Steps in R (featuring rvest & RStudio “Projects”)

November 27, 2014 | hrbrmstr

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 sequential one[1] caused sufficient ... [Read more...]

Visualizing Historical & Most-likely First Snowfall Dates for U.S. Regions

UPDATE: You can now run this as a local Shiny app by entering shiny::runGist("95ec24c1b0cb433a76a5", launch.browser=TRUE) at an R prompt (provided all the dependent libraries (below) are installed) or use it interactively over at Shiny Apps. The impending arrival of the first ...

Moving The Earth (well, Alaska & Hawaii) With R

November 16, 2014 | hrbrmstr

In a previous post we looked at how to use D3 TopoJSON files with R and make some very D3-esque maps. I mentioned that one thing missing was moving Alaska & Hawaii a bit closer to the continental United States and this post shows you how to do that. The ... [Read more...]

Spending Seized Assets – A State-by-State Per-capita Comparison in R

October 13, 2014 | hrbrmstr

The Washingon Post did another great story+vis, this time on states Spending seized assets. According to their sub-head: Since 2008, about 5,400 police agencies have spent $2.5 billion in proceeds from cash and property seized under federal civil forfeiture laws. Police suspected the assets were linked to crime, although in 81 percent of ...

Plot Me Like a Hurricane (a.k.a. animating historical North Atlantic basin tropical storm tracks)

October 7, 2014 | hrbrmstr

Markus Gessman (@MarkusGesmann) did a beautiful job Visualising the seasonality of Atlantic windstorms using small multiples, which was inspired by both a post by Arthur Charpentier (@freakonometrics) on using Markov spatial processes to “generate” hurricanes—which was tweaked a bit by Robert Grant (@robertstats)—and Gaston Sanchez‘s Visualizing Hurricane ...
