This interactive map uses Mapbox GL to display hexagonal bins that reveal the density of locations across the continental United States. The visualization dynamically requests GeoJSON data from a local server based on the current map bounds and zoom level, coloring each hexagon by its location count, with a categorical color scale ranging from light blue to dark blue. At higher zoom levels, individual location points appear as orange circles, and hovering over a bin triggers a popup showing the exact count. The code uses Mapbox GL’s `addSource`, `addLayer`, and `setData` methods to update both the hexbin and point layers as the user pans or zooms.
