So far, we've created a new map, and we've even added a marker to a spot around the city. But we can extend this concept and use data standard formats in the geospatial space like GeoJSON that will allow us to have a good way to describe these locations.
Luckily, GeoJSON interfaces directly with Leaflet, so we'll have an easy time adding that data to the map, but how can we actually create a GeoJSON document with our locations?
