carto - Animate a Choropleth Map in CartoDB?

I used Torque to animate points over time in CartoDB

I have a map of polygons and I want to animate the changing colors.

Over five years the intensity of the type of incident I'm mapping changes. I can make a slideshow that shows a visualization of each year in an individual choropleth map, but I'd love to be able to animate it in torque instead.

Is this even possible?

Answer

Torque doesn't support polygons... yet! But you can experiment with D3, I took a first stab using D3 and CartoDB to achieve something,
