Regrettably, GeoChart does not offer customization options for markers.
However, you can utilize the google-maps package to achieve this:
npm install google-maps
Incorporate the following code into your project:
import React, { Component } from "react";
import { GoogleMap, Marker } from "google-maps-react";
class CustomMap extends Component {
render() {
const mapStyles = {
width: "100%",
height: "100%",
};
return (
<div style={mapStyles}>
<GoogleMap
google={this.props.google}
zoom={10}
initialCenter={{ lat: 37.7749, lng: -122.4194 }}
>
<Marker
position={{ lat: 37.7749, lng: -122.4194 }}
icon={{
url: "path/to/your/custom/icon.png",
scaledSize: new window.google.maps.Size(50, 50),
}}
/>
</GoogleMap>
</div>
);
}
}
export default GoogleApiWrapper({
apiKey: "YOUR_API_KEY",
})(CustomMap);
Replace YOUR_API_KEY with your actual API key.
Don't overlook to display your map within your application:
import React from "react";
import CustomMap from "./CustomMap";
function App() {
return <CustomMap />;
}
export default App;
Although the google-maps-react library does not directly support coloring countries or areas on the map, you can achieve this by utilizing the Google Maps JavaScript API.
To color countries or areas on the map, you can utilize the Data Layer feature of the Google Maps JavaScript API. Here's an example of how you can modify your code to implement this:
import React, { Component } from "react";
import { GoogleApiWrapper, Map, Marker } from "google-maps-react";
class CustomMap extends Component {
constructor(props) {
super(props);
this.mapRef = React.createRef();
}
// Continue with the code as per the provided example...
To change the color of the earth and other areas on the map:
import React, { Component } from "react";
import { GoogleApiWrapper, Map, Marker, DataLayer } from "google-maps-react";
class CustomMap extends Component {
constructor(props) {
super(props);
this.mapRef = React.createRef();
}
// Continue with the code as per the provided example...
