Meziantou.FrameworkGeoMark<T> Class
Draws a geometry per row on a map: its polygons are filled (a choropleth when the Mark<T>.Fill channel is mapped by the color scale), its lines are stroked and its points are dots. The plot uses GeoCoordinates by default when it has a geo mark.
public sealed class GeoMark<T> : Mark<T>Type parameters
T- The type of the rows, such as
GeoFeature.
Remarks
Without a fill, the polygons are light gray, a base map; a row whose fill value is missing is light gray too. The polygons are filled with the even-odd rule, so their holes stay empty whatever the order of their rings. The mark draws only in geographic coordinates. A GeoGeometryCollection draws each of its geometries.
