Laravel – GEO Chart Example using lavacharts

Preview:

Step 1: Installation

In first step we have to download lavacharts package for generate chart file from view blade file. So first run bellow command in your terminal:

composer require khill/lavacharts

Now open config/app.php file and add service provider.

'providers' => [
	....
	KhillLavachartsLaravelLavachartsServiceProvider::class,
]

Step 2: Add Table and Model

we require to create new table “country_users” that way we will get data from this table, you can use your own table but this is for example. we have to create migration for country_users table using Laravel 5 php artisan command, so first fire bellow command:

php artisan make:migration create_country_users_table

After this command you will find one file in following path database/migrations and you have to put bellow code in your migration file for create country_users table.

use IlluminateDatabaseSchemaBlueprint;
use IlluminateDatabaseMigrationsMigration;

class CreateCountryUsersTable extends Migration
{

    public function up()
    {
        Schema::create('country_users', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->integer('total_users');
            $table->timestamps();
        });
    }

    public function down()
    {
        Schema::drop("country_users");
    }
}

After craete “country_users” table you should create CountryUser model for country_users, so first create file in this path app/CountryUser.php and put bellow content in CountryUser.php file:

app/CountryUser.php

namespace App;

use IlluminateDatabaseEloquentModel;

class CountryUser extends Model
{

    public $fillable = ['name','total_users'];

}

Ok, now you can add few records like as bellow :

Step 3: Add Route

In this is step we need to add route for generate view. so open your app/Http/routes.php file and add following route.

Route::get('laracharts', 'ChartController@getLaraChart');

Step 4: Create Controller

Ok, now we should create new controller as ChartController in this path app/Http/Controllers/ChartController.php. Make sure you should have country_users table with some data. this controller will manage data and chart data and view file, so put bellow content in controller file:

app/Http/Controllers/ChartController.php

namespace AppHttpControllers;

use IlluminateHttpRequest;
use KhillLavachartsLavacharts;
use AppCountryUser;

class ChartController extends Controller
{

    public function getLaraChart()
    {
    	$lava = new Lavacharts; // See note below for Laravel

		$popularity = $lava->DataTable();
		$data = CountryUser::select("name as 0","total_users as 1")->get()->toArray();

		$popularity->addStringColumn('Country')
		           ->addNumberColumn('Popularity')
		           ->addRows($data);

		$lava->GeoChart('Popularity', $popularity);

        return view('laracharts',compact('lava'));
    }

}

Step 4: Create View File

In last step, we have to create view file “laracharts.blade.php” for generate view chart, so create laracharts file and put bellow code:

resources/view/laracharts.blade.php

<div id="pop-div" style="width:800px;border:1px solid black"></div>
<?= $lava->render('GeoChart', 'Popularity', 'pop-div') ?>

Now you can run and check.
