Angular Google Charts - Map Chart Using Lattitude/Longitude

Following is an example of a Map Chart using Latitude/Longitude.

We have already seen the configurations used to draw a chart in Google Charts Configuration Syntax chapter. Now, let us see an example of a Map Chart using Latitude/Longitude.

Configurations

We've used Map value to show Google Map based chart.

type = ChartType.Map;

In order to enable Google Map integration, we're required to pass on API KEY procured from Google Cloud Console in app.config.ts under provideGoogleCharts() as shown below.

app.config.ts

import { ApplicationConfig, provideBrowserGlobalErrorListeners, provideZonelessChangeDetection } from '@angular/core';
import { provideRouter } from '@angular/router';

import { routes } from './app.routes';
import { provideGoogleCharts } from 'angular-google-charts';

export const appConfig: ApplicationConfig = {
  providers: [
    provideBrowserGlobalErrorListeners(),
    provideRouter(routes),
    provideGoogleCharts( {
      version: '49', 
      mapsApiKey: 'API_KEY', 
      safeMode: true
    }),
    provideZonelessChangeDetection(),
  ]
};

Example - Usage of a Map Chart with Latitude/Longitude.

app.ts

import { Component, signal } from '@angular/core';
import { ChartType, GoogleChart } from 'angular-google-charts';

@Component({
   selector: 'app-root',
   imports: [GoogleChart],
   templateUrl: './app.html',
   styleUrl: './app.css'
})
export class App {
   protected readonly title = signal('google-charts-app');
   type = ChartType.Map;
   data = [
      [37.4232, -122.0853, "Work"],
      [37.4289, -122.1697, "University"],
      [37.6153, -122.3900, "Airport"],
      [37.4422, -122.1731, "Shopping"]
   ];
   columnNames = ["Latitude","Longitude","Name"];
   options = {  
      showTip: true
   };
   width = 550;
   height = 400;
}
