Configure a drill
A powerful feature of the Mapchart is its capacity to disclose information step-by-step.
By configuring a drill, you'll let your user go through hierarchized data with a simple and intuitive interface.
1. Prepare data
You don't have to prepare your data specifically to have a drillable mapchart. You just have to join your dataset and your geojson file for a basic mapchart.
2. Configure the drill hierarchy
Go to the "Drill" section in your mapchart's configuration form.
Declare your columns from the bigger to the smaller level
