Analysis of The Washington Post's Fatal Police Shootings database

The Washington Post has been collecting data about fatal police shootings since 2015 until present. The data is hosted here on Github and is regularly updated. The purpose of this project is to explore that data and create interactive visualizations for anyone to use and interpret.
This project is split into 3 notebooks:
- DataPreparation.ipynb: Load the dataset, take a initial look at the columns, print out basic info. Geocode cities/states into latitude/longitude coordinates. Create new columns that will make plotting easier.
- FindIncorrectCoord.ipynb: Visualize geocoding errors.
- PoliceShootingsAnalysis.ipynb: Main notebook that creates several visualizations of the data using plotly
There is also a utils.py file that contains code that geocodes cities, adds missing coordinates, fixes incorrect coordinates, and serializes data. In addition to this all the plots (except the map plots) are downloaded as png files and stored in the plots folder.
Plotly plots don't render correctly when viewed in Github, so the best way to view the notebooks that use plotly is to view them on nbviewer.jupyter.org. Below are links to view the notebooks on that website. Also the geographic map in PoliceShootingsAnalysis.ipynb has a small bug where if you press the button that says "years," the plot becomes emtpy. Just click and move the slider to fix this and the data points will appear. The same may happen when pressing the "states" button, just click on one of the state names on the right and the points should appear.
