choropleth_ldn
Simple script to create a chloropleth map of London with categorical timeseries data.
The script in main.py creates a gif of the most frequent animal types rescued by the London Fire Brigade over the
years, by borough.
This is what that looks like:
It also performs some cleaning of the dataset, i.e.:
- removing boroughs that are not part of Greater London.
- replacing animal entries that are “Unknown – …” e.g. “Unknown – Heavy Livestock Animal” to just “Unknown”.
As a quick note, there are better ways to create gifs that don’t involve saving down individual frames. However, I
wanted to be able to look at the frames on their own as well.
How to run
Install the required libraries by running pip install -r requirements.txt or conda install --file requirements.txt.
Create a folder called fig. This is where the script saves individual frames and the final gif.
Then run main.py.
