Those prickly eyebrows
Motion-sick, or just sick?

Reading the landscape

Here are some posts I find worth reading on other graphics blogs:

Nick has done wonderful work on the evolution of the rail industry in the U.S., with a flow chart showing how mergers have produced the four giants of today, as well as a small multiples of maps showing how they split up the country.

A lovely feature of the flow chart is the use of red lines to let readers see at a glance that Union Pacific is the only rail company that has lasted the entire 4 decades, while the other 3 giants came into being within the last 20 years.

On the maps, notice a slight inconsistency between the left and right columns: on the right side, both maps have the same set of anchor cities, which act as "axes" to help readers compare the maps; on the left side, the sets of anchor cities are not identical. It would also be interested to see a version with all four route maps superimposed and differentiated by color. That may bring out the competitive structure better.


Georgette has a nice post summarizing issues with picking colors when producing charts. Her blog is called Moved by Metrics.


Meanwhile, Martin finds a shockingly poor pie chart here.


There was a time where you'd find the kind of heatmaps featured here by Nathan as wallpaper in my office. It's a great visualization tool for exploring temporal patterns in large data sets. However, I'd never even think of putting these in a presentation.  It's a starting point, not an end-point, of an analysis project. Some things are wonderful for consumption only in private!

Hi Amanda, cool post...


Great post. Thanks Nick for your help. Kudos to you.


The pie is no longer actual to the dated time, make new post regarding this issue.
