This interactive web application enables users to create, view, and share spatial data as GeoJSON. The interface combines a Mapbox GL-powered map with a text editor, allowing real-time synchronization between geographic features and their JSON representation. The code uses Mapbox GL JS for map rendering and tile loading, along with React for building the UI components. The application supports drawing, editing, and parsing GeoJSON geometry, with changes reflected instantly across both the map and the editor panel.
