Create interactive sf objects
These geometries are based on geom_sf(), geom_sf_label() and geom_sf_text().
See the documentation for those functions for more details.

The interactive parameters can be supplied with two ways:
As aesthetics with the mapping argument (via aes()).
In this way they can be mapped to data columns and apply to a set of geometries.
As plain arguments into the geom_*_interactive function. In this way they can be set to a scalar value.
