Mapbox Data Visualization Patterns

This covers the main ways to visualize data on Mapbox maps: choropleth maps for regional statistics, heat maps for point density, 3D extrusions for height data, and animated time series. The patterns are practical, showing when to use interpolate versus step for color scales, how to add hover popups without recreating them on every event, and zoom-dependent layer switching so heat maps transition to points at close range. It includes the data size rule that matters (under 1MB use GeoJSON, over 10MB switch to vector tiles) and references for clustering, animation, and performance optimization. The color accessibility section is worth reading if you're working with public-facing maps.
