3D Air Quality Maps With Neo4j, Python, and R

Air quality across the Pyrenees corridor is a pressing concern, particularly during summer heatwaves and wildfire seasons. In this region, cities on both sides of the French-Spanish border share air masses, making cross-border analysis a natural fit for a graph database. In this article, we’ll build a pipeline that fetches real-time air quality data from the IQAir API, stores it in Neo4j as a graph, and produces complementary views of the data:
