I think I got it following this example:
Here’s the code:
let data_geojson_layer = L.geoJson(data_geojson, {
onEachFeature: function(feature, layer){
console.log(feature.properties);
var content = "Project: " + feature.properties["Mining_Pro"];
layer.bindPopup(content);
}
I’ve also updated the notebook. If there’s a better way of doing this, please let me know!
