Aspect Ratio and Banking to 45 Degrees

Robert Kosara has an interesting piece about the “banking to 45-degrees” phenomena in line-charts and its origin in a 1988 paper. What people often miss, however, is what task Cleveland and the McGills were after.

Meet @InfoVis_Ebooks, Your Source for Random InfoVis Paper Snippets

Robert Kosara (eagereyes) has written a fun little tool that posts random text from InfoVis papers at major conferences on twitter at the @InfoVis_Ebooks account. Each tweet contains a reference to the paper the snippet is from. For InfoVis, VAST, and CHI, these are DOIs rather than links. Links get long and distracting, whereas DOIs […]

The State of Information Visualization, 2011

Robert Kosara has a great piece on what he thinks will happen in the field of Information Visualization this year, and it’s a bit of a surprise.  It won’t be algorithms, it won’t be The Cloud, it won’t even be open data:  It will be Microsoft’s IE9. But another development will actually be much more […]

Federal Taxes and Debt

I have followed Doug Short for a number of years now via some of his graphs posted on Calculated Risk. I especially love the fact that he has compared the crash of 1929, with the 1973 oil crisis, the 2000 tech crash, and the 2007 financial crash in a nice visualization. Recently he has been […]


Stacked Bar Chart Alternatives

I cannot stand a stacked bar chart for one simple reason. The stacked bar chart has only one common baseline. Thus you can only compare variables along that one common baseline. The rest of the variables do nothing except to clutter up the chart. I have wanted to do a post against stacked bar charts […]

Visualizing Names

Hades: So you took care of him, huh? “Dead as a doornail.” Weren’t those your *exact* words? Pain: This might be a different Hercules. Panic: Yeah. I mean, Hercules is a very popular name nowadays. Pain: Remember, like, a few years ago, every other boy was named Jason, and the girls were all named Brittany? […]

Visualizing IPv4 addresses on the Internet

Did you know that there is less than 950 days (2.6 years) until regional registry IPv4 address exhaustion? There are 4,294,967,296 addresses (or about 28.8 adresses per square kilometer of land) for IPv4. Thus we need to moving towards IPv6 which gives us 2128 addresses (or about 2.2 x 1024 adresses per square meter of land). […]
Unemployment on a County Level

When Did Your County’s Jobs Disappear?

Slate has taken the Local Area Unemployment Statistics from the U.S. Bureau of Labor Statistics to create an information visualization showing the jobs lost over the past two years. Blue circles indicate that jobs were gained. Red circles indicate that jobs were lost. The size of the circle indicates the magnitude of change. The visualization […]

When looking at the forecast by state, Texas looks to improve by 1.3% while Nevada continues to plummet by 1.9%. If […]

EagerEyes’ The State of Information Visualization

Robert Kosara, known to many as @EagerEyes, has written up his views on Information Visualization and access to data in 2009, and where he thinks 2010 is going. In addition to the practical visualization uses, 2010 might be the year of visualization theory. While our field is certainly an applied one, we still need a […]


Bad Vis: Counterinsurgent Strategy in Afghanistan

Do you ever wonder: “What the United State’s strategy for dealing with the insurgency in Afghanistan?” Do you ever wonder: “How do people come up with such bad visualizations?” Thanks to the PA Consulting Group, we get to see both at the same time. Richard Engel, NBC News Chief Foreign Correspondent, obtained an unclassified briefing […]
