An analysis of outdoor rock climbing data
For each zipcode in the United States, we calculate that zipcode's climbing score using the following formula.
After creating a score for each zipcode, we then create the heatmap using Matplotlib in conjunction with shapefiles provided by the 2017 US Census.
Since not every area in the US is covered by a zipcode, we use US counties as a fallback which are less granular than zipcodes but cover all areas in the US.
