Visualizing Chicago Crime Landscape

Challenge

Chicago has a reputation of being one of the most violent cities in America. This perception is skewed by the size of the population of Windy City where the homicide rate per 100,000 residents is much lower than in cities like New Orleans, Detroit or St. Louis. But any way you look at it, the number of shooting incidents in Chicago is staggering, with an average of 12 people being shot every single day (2016). City of Chicago provides detailed data on each crime committed in the city since 2011. But how do you visualize over 6 million records from the last decade and a half?

Solution

This visualization was one of the favorites in the 2015 Tableau IronViz feeder contest. The main challenge was handling over 6 million records of data imported from the City of Chicago data portal. We created a comprehensive set of dashboards providing insight into geographic distribution of crime incidents in the city, as well as an analysis of seasonality of crimes, and day of week/hour patterns. We also looked and the long-term trends in crime occurrence and the impact of violent crimes on property prices in the city. We used a striking design with red dominating on a black background to emphasize the seriousness of the topic.
