Dynamic pie charts are an excellent way to visualise data in online applications. They depict data composition and distribution in a straightforward and succinct manner. The combination of Laravel, a sophisticated PHP framework, and JavaScript tools such as Highcharts makes it simple to construct dynamic pie charts.

We will walk you through the process of constructing a dynamic pie chart in Laravel 10, allowing you to show and update data in an interactive and visually pleasing manner.

Throughout this article, we will look at how to build up a Laravel project, integrate Highcharts, and create dynamic pie charts that can fetch and display data in real-time.

Let’s get started.

Laravel Installation

Open terminal and run this command to create a laravel project.

composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

Create Database & Connect

To create a database, either we can create via Manual tool of PhpMyadmin or by means of a mysql command.

CREATE DATABASE laravel_app;

To connect database with application, Open .env file from application root. Search for DB_ and update your details.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel_app
DB_USERNAME=root
DB_PASSWORD=root

Setup Model & Migration

Open project terminal and run this command,

php artisan make:model BrowserStat -m

It will create two files –

Model – BrowserStat.php inside /app/Models folder
Migration file – xxx_create_browser_stats_table.php inside /database/migrations folder.

Open migration file and write this complete code into it.

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up(): void
    {
        Schema::create('browser_stats', function (Blueprint $table) {
            $table->id();
            $table->string("name", 30);
            $table->float("total_usage");
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down(): void
    {
        Schema::dropIfExists('browser_stats');
    }
};

Open model file BrowserStat.php and write this complete code into it,

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class BrowserStat extends Model
{
    use HasFactory;

    public $timestamps = false;
}

Run Migration

Back to terminal and run this command.

php artisan migrate

It will create browser_stats table inside database.

Next,

Create Laravel Data Seeder

Create a seeder file to seed some dummy data for table.

Run this command to terminal –

$ php artisan make:seeder BrowserStatSeeder

It will create a file BrowserStatSeeder.php inside /database/seeders folder.

Open file and write this complete code into it,

<?php

namespace Database\Seeders;

use Illuminate\Database\Console\Seeds\WithoutModelEvents;
use Illuminate\Database\Seeder;
use App\Models\BrowserStat;

class BrowserStatSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run(): void
    {
        $data = [
            array(
                "name" => "Chrome",
                "total_usage" => 64.02
            ),
            array(
                "name" => "Firefox",
                "total_usage" => 12.55
            ),
            array(
                "name" => "IE",
                "total_usage" => 8.47
            ),
            array(
                "name" => "Safari",
                "total_usage" => 6.08
            ),
            array(
                "name" => "Edge",
                "total_usage" => 4.29
            ),
            array(
                "name" => "Others",
                "total_usage" => 4.59
            )
        ];

        BrowserStat::insert($data);
    }
}

Run Seeder File

Run this command to terminal.

php artisan db:seed --class=BrowserStatSeeder

It will create test data into database table.

Create Data Controller

Next, we need to create a controller class,

php artisan make:controller BrowserController

It will create a file BrowserController.php inside /app/Http/Controllers folder.

Open file and write this complete code into it.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\BrowserStat;
use Illuminate\View\View;

class BrowserController extends Controller
{
    public function index(): View
    {
        $browsers = BrowserStat::all();

        $dataPoints = [];

        foreach ($browsers as $browser) {

            $dataPoints[] = [
                "name" => $browser['name'],
                "y" => floatval($browser['total_usage'])
            ];
        }

        return view("pie-chart", [
            "data" => json_encode($dataPoints)
        ]);
    }
}

Create Blade Template File

Go to /resources/views folder and create a file with name pie-chart.blade.php

Open file and write this complete code into it.

Add Route

Open web.php file from /routes folder. Add this route into it.

//...

use App\Http\Controllers\BrowserController;

//...

Route::get('browser-usage', [BrowserController::class, 'index']);

//...

Application Testing

Run this command into project terminal to start development server,

php artisan serve

URL: http://127.0.0.1:8000/browser-usage

Once we open this URL, Pie Chart will be generated using Highchart plugin.

Output

That’s it.
