Chicago’s Prostitution Decline 2001 – 2017 (revisited)

Visualizing the decline of Chicago prostitution from the eyes of the police department. The time range used spans from 2001 through 2017. The data was filtered from data.cityofchicago.org. Below is a Torque/Geo Temporal Map which animates over time using 67,690 total incident reports, each report with a primary crime type of prostitution. Beneath that is a cumulative heat map. And lastly, a map created attempting to show the migration of enforcement over years.

Close Packing Defect Formations (crystal formation)

Visualizing the formation of Close-packing defects using equal spheres.

I rolled a bunch of balls into a closed container. The top of the container is invisible and only tall enough to fit one layer of balls. once the balls finish falling, they arrange themseleves into some pretty interesting patterns.

All the usual suspects showed up:
– Point Defects, Crystallographic defect (Highlighted by different colors)
– Grain Boundaries, Lattice Regions seperated by different angles.

Below are a couple animations I rendered displaying the formation of the interesting lattice patterns.
