I love me some graphs

Especially interactive graphs.

GE made a graph of the average annual cost of patients with eleven common chronic diseases.  Go check it out, marvel at the coolness as you grab the sliders and spin the wheel o' misfortune. 

Take home point: hypertension is the single biggest driver of medical cost in all patients age 33 and up.  Go figure.

Very cool- I am so going to use this and share it with clients- I am something of a data wonk IRL- and write a lot of justifications to fund FQHCs for preventative care and chronic disease management programs- this graphic is just terrific. Thanks for sharing it.

Great site. Although your graph today made me dizzy! LOL

Just started my own site as well--writing more from a human nature perspective. I'm checking out other blogs to see what's out there and I liked yours.

WEll done. I'll be following.

It's fascinating to watch the costs grow and shrink vs. ages. Thanks for posting this.

This graphic is fun to play with, which should attract attention to the cost of chronic diseases. But GE's site needs to have an explanation somewhere about what the pie means, in particular why the pieces have different depths/lengths.

In a normal pie chart, the % of overall cost would be represented by the angle of the slice. So if asthma has a right angle (90 degrees), it represents 25% of the total cost. The overall size of the pie, which changes as I move the age slider, presumably represents total expenditure. That's what I can figure out, although it would be nice if the page explicitly stated these meanings.

But the real problem is that in this pie, the radius of the pieces differ, giving it a jagged rounded circumference. For example, when you first load up the graphic, two gray spikes stick way out-- Emphysema and Gastric Ulcer. Why? What does this axis represent? I'm especially confused when diseases with wide chunks of pie (big angles) are much shallower than other slices. Are these big expenditures or not?
