Indeed, this set of maps produced by Doug Mccune (more here) using publicly available data released by the San Francisco government on its DataSF website is breathtakingly beautiful. Thanks to Rudy R for bringing this to our attention.

Hate to spoil the fun but it has to be said that if we apply the Trifecta checkup, these maps fail at the first question: what is the practical issue being addressed?
As Doug noticed, there is a ridge along Mission Street that appears on pretty much every map regardless of the type of crime. The features on various maps are rather consistent as well -- and I can assure you that those features are consistent with population density.
Alas, if you live in San Francisco and care about crime there, Mission Street is not news. We don't need a sophisticated map to tell us that insight. Same with where prostitution is.
What if you are interested in crime in your local neighborhood? Not these maps either because in creating the relief, Doug must make approximations; the higher the peak, the more collateral activity is created around the peak to avoid discontinuities in the surface. This destroys the local details.

Still, they are gorgeous to look at, and as Doug alluded to in his disclaimer, we just need to remove our junkcharts glasses to appreciate them.
