How can I add GeoJSON data to my maps?

You can add GeoJSON data to your maps by using libraries like Leaflet or Mapbox. Do you have a specific library in mind?

I'm using Leaflet. Can you give me a code example?

Sure! Here's a simple example:

var map = L.map('map').setView([51.505, -0.09], 13);

L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
    maxZoom: 19,
}).addTo(map);

var geojsonFeature = {
    "type": "Feature",
    "properties": {
        "name": "Coors Field",
        "amenity": "Baseball Stadium",
        "popupContent": "This is where the Rockies play!"
    },
    "geometry": {
        "type": "Point",
        "coordinates": [-104.99404, 39.75621]
    }
};

L.geoJSON(geojsonFeature).addTo(map);

This will add a point to your map. Would you like to know more about styling?

Yes, how can I style the GeoJSON features?

You can style GeoJSON features by using the style option in the L.geoJSON method. For example:

L.geoJSON(geojsonFeature, {
    style: function(feature) {
        return {color: feature.properties.color};
    }
}).addTo(map);

You can define colors in the properties of your GeoJSON. Do you need help with anything else?
