H3 aggregation settings
H3 aggregation settings is the first group of Appearance.
- H3 resolution (0 to 15) sets the size of the hexagon areas. The default is 7. A higher number gives smaller areas.
- Background map URL template adds a background map. Use a tile template with z, x, and y placeholders, or a WMS GetMap template with bbox, width, and height placeholders.
- Background map attribution adds the credit text under the map.
The country outline uses Natural Earth country borders at 1:50m scale. It needs no credit and makes no network request. The shared settings set text size, colors and legend, and tooltip.
