Creating a featurelayer from an array of locations

Hello!

I was wondering if it would be possible to turn a 2d array of latitude and longitude into a featurelayer using esri leaflet? Would this be difficult to accomplish? This is what the data looks like:

var data = [ { "latitude": 59.441193, "longitude": 24.729494 }, { "latitude": 59.432365, "longitude": 24.742992 }, { "latitude": 59.431602, "longitude": 24.757563 }, { "latitude": 59.437843, "longitude": 24.765759 }, { "latitude": 59.439644, "longitude": 24.779041 }, { "latitude": 59.434776, "longitude": 24.756681 } ];

You could use Add XY Coordinates in ArcMap to convert the table of coordinates to points, and then share the result as a map. Leaflet can be used to publish it, but isn't required.

LeafletJS is pretty open-ended here with a few ways you could accomplish this. But with the esri-leaflet plugin there is no concept of a "client-side-only" FeatureLayer (but there is in the ArcGIS API for JavaScript).

Back to LeafletJS itself, you can use layer types such as `Marker`, `Circle`, or `CircleMarker` with each of your objects in your data array.
