geom_histogram should not try to handle geometries in GeoDataFrame

[alshan]

ggplot() + geom_histogram(aes(x='price'), data=merged_areas)

Fails with the error: "geometry not found in data".

ggplot(merged_areas) + geom_histogram(aes(x='price'))

Works just fine.

The 'merged_areas' is a GeoDataFrame containing the 'price' column, geometry (polygons) and other columns.

Similar situation:

ggplot() + geom_point(aes(x='neighbourhood', y='price'), data=gdf_listings)

Shows a map. Meanwhile, the expected plot was:

Expression:

ggplot(data=gdf_listings) + geom_point(aes(x='neighbourhood', y='price'))

works as expected.
