Step 1: pick what to produce, then configure.
Numeric for Sum/Average; any column for Min/Max.
Tick numeric columns or type an expression (e.g. Quantity*Price, Total/2).
E.g. Quantity*Price, Total/2. In multi-series, each expression becomes an extra series alongside checked columns.
Choropleth on official boundaries (region / division / subdivision).
Search and tick regions. Other regions are hidden and the map zooms in.
