One of the chapters that I had to cut from Visualizing Data was about scenarios—building interactive “what if” tools that help you quickly try out several possibilities. This is one of the most useful aspects of dynamic visualization—being able to try out different ideas in a quick way (and safe, as in non-destructive, since Undo is always nearby). Hopefully I’ll be able to cover this sometime soon.
At any rate, one such scenario-building tool is Slate’s Delegate Calculator, where you can drag primitive sliders back and forth and see the possibilities for delegate outcomes for Hillary and Obama.
I’ve seen complaints about its math, but it seems to do an OK job for a big-picture look at the likelihood of different outcomes. Getting the math 100% is impossible (unless you have a far more complicated interface) because the delegate selection process is different in each state. It appears that none of the states wanted to be seen using the same approach as another, and with fifty states going their own way, things got pretty random (Texas: we’ll have a caucus and a primary).
I think that’s enough posting about politics for a bit.
