This is really cool, I'll definitely look at this if I need to embed a map in the future. Are there any libraries that lets you plot geographic data on top of this in Python, with Matplotlib or similar?

Slightly off topic, but how come there doesn't seem to be any open projects using the Overture maps data?

> Overture is a data-centric map project, not a community of individual map editors. Therefore, Overture is intended to be complementary to OSM. We combine OSM with other sources to produce new open map data sets. Overture data will be available for use by the OpenStreetMap community under compatible open data licenses. Overture members are encouraged to contribute to OSM directly.

Sounds like it would be a good data source, or am I missing something?

Overture is an awesome resource because it has more coverage than OSM, but at the cost of accuracy. When I was considering using it for restaurants in surprisedatespot.com, I found that it has a lot more automated content with bad geocoding (imprecise locations) compared to OSM.

E.g. restaurants can come from an old Facebook page and the geocoding might not be accurate compared to a survey.

So where OSM might have a restaurant that closed 8 years ago, overture has every restaurant that's been at that location for the past 8 years.

Folium is a useful library for plotting geographic data in Python. It generates a webpage with the map data displayed with Leaflet.js

I develop Lonboard [0], a Python library for plotting large geospatial data. If you have small data (~max 30,000 coordinates), leaflet-based Python libraries like folium and ipyleaflet can be fine, but because Lonboard uses deck.gl for GPU-accelerated rendering, it's 30-50x faster than leaflet for large datasets [1].
