title: Freehand Drawing
shortdesc: Example using the ol.interaction.Draw interaction in freehand mode.
docs: >
  This example demonstrates the `ol.interaction.Draw` in freehand mode.  During
  freehand drawing, points are added while dragging.  Set `freehand: true` to
  enable freehand mode.  Note that freehand mode can be conditionally enabled
  by using the `freehandCondition` option.  For example to toggle freehand mode
  with the `Shift` key, use `freehandCondition: ol.events.condition.shiftKeyOnly`.
