# series.mapline.data.geometry

For map and mapline series types, the geometry of a point.

To achieve a better separation between the structure and the data, it is recommended to use `mapData` to define the geometry instead of defining it on the data points themselves.

The geometry object is compatible to that of a `feature` in GeoJSON, so features of GeoJSON can be passed directly into the `data`, optionally after first filtering and processing it.

For pre-projected maps (like GeoJSON maps from our map collection), user has to specify coordinates in `projectedUnits` for geometry type other than `Point`, instead of `[longitude, latitude]`.
