I have some GIS data that I'm trying to plot with Python. One feature at a time works fine,[^credit] but I'd like to have two (or multiple) datasets on the same map.
```py
import matplotlib
import geopandas as gpd
import contextily as ctx
points = gpd.read_file('points.geojson')
points = points.to_crs('EPSG:4326')
# Snipped a bunch of filtering/adjustment here.
ax = points.plot(figsize=(15, 15), markersize=20)
ctx.add_basemap(ax, crs=points.crs, source=ctx.providers.CartoDB.Positron)
# Can I add some other shapes before the render?
~~with open('render.png', 'wb') as img:~~
~~img.write(ax.set_axis_off())~~
```
I'm pretty comfortable with slippy maps on Leaflet, but I'm trying to get these[^several] as single rendered images.

Add additional shapes on a GeoPandas matplotlib

I have some GIS data that I'm trying to plot with Python. One feature at a time works fine,[^credit] but I'd like to have two (or multiple) datasets on the same map.

```py
import matplotlib
import geopandas as gpd
import contextily as ctx

points = gpd.read_file('points.geojson')
points = points.to_crs('EPSG:4326')

# Snipped a bunch of filtering/adjustment here.

ax = points.plot(figsize=(15, 15), markersize=20)
ctx.add_basemap(ax, crs=points.crs, source=ctx.providers.CartoDB.Positron)

# Can I add some other shapes before the render?

with open('render.png', 'wb') as img:
    img.write(ax.set_axis_off())
```

I'm pretty comfortable with slippy maps on Leaflet, but I'm trying to get these[^several] as single rendered images.
