November 26, 2014The composition of the U.S. House of Representatives provides great material for data visualization. We’ve already produced a graph (click here for the original post, here for the improved version) that, like the Minard graphic of Napoleon’s march to Moscow popularized by Edward Tufte, presents seven types of data in a single two-dimensional space. It paints a rather complete picture. But does it really feed the bulldog?
November 24, 2014Let’s take a little more time to consider the question of choosing a health insurance policy. In my last post we looked at these choices:
November 19, 2014We shift gears from recent posts to address a critical – and extremely timely – decision: choosing a health insurance plan, which you must do by 12/15 if you want a new plan in place by 1/1/15.

October 22, 2014Today’s USA Today story about last night’s World Series game (GO GIANTS!) includes an interesting graphic, showing the success of “wild card” teams since they were first included in Major League Baseball’s postseason playoffs in 1995. 2014 is the first year that two wild card teams have faced off in the World Series – yes, a major-league record!!!

June 26, 2014This week I had the privilege of presenting at the Institute of Management Accountants Annual Conference in Minneapolis. They are a great audience for my “Painting with Numbers” message and I thoroughly enjoyed interacting with the IMA members.
