Annotating gv.Path

[philippjfr]

The GeoAnnotator classes were really meant as templates, which should be modified and/or expanded depending on a users needs. It should be very straightforward to add a parameter to the GeoAnnotator to switch between gv.Polygons and gv.Path.

That seems easier said than done, as least for me, but I'm making an attempt.

Do you mention switching between gv.Polygons and gv.Path because BOTH cannot be drawn at the same time (i.e. you can't have two PolyDraw objects on one drawing)?

[philippjfr]

In the simple case you could just let a user switch between them by making the following changes/additions to GeoAnnotator:

geometry_type = param.ClassSelector(default=gv.Polygons, class_=gv.Path)

def __init__(self, polys=None, points=None, **params):
    ...
    self.polys = self.geometry_type(polys, crs=ccrs.GOOGLE_MERCATOR)
    ...

If you want to draw and annotate both polygons and paths a slightly more complex implementation would be needed.
