How can I create heatmaps of geographic data, without relying on an external web service or API?

I've got a large, ever-changing dataset that includes geographic data from almost every country. The data include lat/lon coordinates, ISO country codes, city/region name, and a count (number of "incidents" reported).
As part of a larger, web-browser-based dashboard, I'd like to create a heatmap showing which countries / regions have the most incidents. But, for various reasons, the web server this is on doesn't always have the ability to talk out to the Internet, so it can't rely on an external service, like Google Maps.
Is there a standalone, free-and-open-source package that would let me do this? Needs to run on a linux server with nginx, and bonus points if it's Python.
