Notebooks using DuckDB with the H3 Extension and Overture Maps Data

The latest DuckDB 1.1.0 now reads geoparquet natively. So that means all of these queries with ST_GeomFromWKB will break

I am going to update them soon but for now just take out ST_GeomFromWKB()

In montpelier_water_buildings.ipynb, I visualize the volume of buildings near water.

In egypt_building_density.ipynb I look at building density.
