Geometry type:

Example of using the ol/interaction/Draw interaction with drawing style configured.

The Draw interaction in this example uses a custom drawing style. Select a geometry type from the dropdown above to start drawing. To finish drawing, click the last point. To activate freehand drawing for lines, polygons, and circles, hold the `Shift` key.
