GeoJSON is a JSON format that encodes geometries. GeoJSON can encode points, line strings, and polygons. It also allows for multipart geometries. You can encode multipoints, multiline strings, and multipolygons. These should sound familiar because they are pretty close to the geometries you learned to draw in Chapter 1, Creating Maps with Leaflet.

{"type":"FeatureCollection",
"features":[

"properties":{
"name":"MyOther Point",
"title":"A point near Moriarty...
