Back to Mapbox elections
Real-time mapping solution
This solution enables advanced users to build performant and lightweight, real-time data-join using Mapbox. In other words, we’re making it easier for you to join a live dataset — like the reporting of election returns by county — to geometries in a Mapbox tileset.

When joining spatial data on the fly, users often need to generate long expressions in order to visualize the data on a map, and if the dataset is large, the process can be slow. This solution offers a performant approach to data-join, using Mapbox GL JS feature-state. Head to the solution page to learn more.
