'Tableau choropleth for crime data using custom shapefile
I've been working with some crime data from Kaggle. I've been able to produce bar charts and scatter plots grouped by police district. The data has individual records for each incident and the lat/long. https://www.kaggle.com/datasets/currie32/crimes-in-chicago
I started working with maps and managed to get Tableau to plot every crime location on the base map with filters for year and "primary type". Now I want to create a choropleth by police district. I've tried linking the data source to the shapefile in Data > Edit Blend Relationship then link the district numbers. Not sure of the next steps.
I have been using the shapefile from this site: https://data.cityofchicago.org/Public-Safety/Boundaries-Police-Districts-current-/fthy-xz3r
I haven't been able to find any tutorials about building a choropleth using a custom spatial file. Any suggestions?
