This repo contains a data set from the Chicago Police department for crimes committed between 2001 to the present(with the exception of murders where data exists for each victim). This project is dedicated to doing some cool data analysis and visualization on this already curated dataset.
Data visualizations were created through the super awesome Python library folium, which I highly recommend to make beautiful map visualizations.
Some visualizations were not able to render properly in jupyter notebook, but I have saved all of the visualizations (and some more) as html files in the visualization folder.
There are some more in depth visualizations located in that folder as well, such as all Chicago crimes reported in 2018 so far. Descriptions of each map visualization is shown below:
- 2018-chicago-crimes.html: This map is a detailed map visualization of all the crimes commited in Chicago from Jan. 1, 2018 to March 19, 2018, with popup markers that display more information about each individual map, such as date, time, location, crime type, and crime description.
- 2018-chicago-crime-heatmap.html: This map contains a heat map of all the crimes commited in Chicago from Jan. 1, 2018 to March 19, 2018.
- March-2018-chicago-crimes.html: This map is a detailed map visualization of all the crimes commited so far in the month of March (March 1, 2018 to March 19, 2018), with popup markers that display more information about each individual map, such as date, time, location, crime type, and crime description.
- March-2018-chicago-crime-heatmap.html: This map contains a heat map of all crimes commited so far in the month of March (March 1, 2018 to March 19, 2018).
- Crime-per-district-choropleth.html: This map contains a choropleth map of all the crimes from 2001 to present (March 19, 2018) based on Chicago Police District
Also, here is the nbviewer for my jupyter notebook where most of the maps are rendered (the visualization occasionally doesn't show up in Chrome, but does show up on Firefox or Safari): Notebook Viewer
