Success! We've imported our data and we're now ready to use it. Luckily, Leaflet makes this part relatively easy.

So how can we add our GeoJSON data to the map?

Colby Fayock: [0:00] To add our location data, the first thing we want to do is get rid of this marker that we already have there. Instead, we're going to create a new constant called GeoJSON, which we're going to say = newLeafletGeoJSON instance where we'll pass in our locations.

[0:11] Since our locations are already made up of a GeoJSON document, Leaflet will already know how to manage that. Similar to our marker, we can say GeoJSON, and we can add it to our map. If we look in our browser, we can see our two locations.
