Use Geojson.io to Draw Custom Marker and Shape Features for a React Leaflet Map

In this lesson, we'll use geojson.io to add markers and draw shapes to create a GeoJSON document that we can add to our React Leaflet map. We'll walk through drawing the shapes, creating a new file to store the GeoJSON data, importing it to our app, and displaying it on our map with the React Leaflet GeoJSON component.
