Map projections translate spherical geography into flat maps. The Mercator projection preserves angles and shapes at a local scale, making it a popular default for web mapping and point-data visualizations.
This sample uses the Mercator projection to plot thousands of Starbucks coffeehouse locations worldwide as marker series grouped by ownership type — Licensed Stores, Joint Venture, and Franchisee. The map features a preloader for the large dataset, detail tooltips showing store name, city, and address, a color-coded legend, and interactive zoom controls.
See the Map Projections documentation for all configuration options.
