Cartographic controls are essential for visualizing dense data during wildfires, as evidenced by the open data from the National Interagency Fire Center, which highlights the scale of wildfires in the Western US. These up-to-date maps are crucial for residents and emergency responders to navigate and understand the disasters, emphasizing the importance of comprehensive data sets, including fire perimeters and evacuation zones. Jonni Walker, a cartographer at Mapbox, is contributing to this effort with a series of posts on cartography, sharing principles and tips for using Mapbox Studio to create effective visualizations.
