Google Pie Charts are an effective approach to illustrate data composition and distribution in online applications visually. To generate dynamic and interactive pie charts, Laravel, a sophisticated PHP framework, can be easily linked with Google Charts.

We will walk you through the process of integrating Google Pie Charts in Laravel 10, allowing you to present data in an appealing and informative manner.

Throughout this article, we’ll look at how to build up a Laravel project, integrate Google Charts, and create dynamic pie charts that can 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 Data Model & Migration

Consider users table to work with this Pie chart tutorial.

By default, you should see the users table migration (2014_10_12_000000_create_users_table.php inside /database/migrations folder) and User.php model in /app/Models.

We will work with these files.

Run Migration

Next, we need to create tables inside database.

php artisan migrate

This command will create tables inside database.

You will also see users table with all tables in database.

Next,

Prepare Dummy Data for Graph

You need to copy the given mysql query and run into sql tab of phpmyadmin. This will give us a set of data to test.

--
-- Dumping data for table `users`
--

INSERT INTO `users` (`id`, `name`, `email`, `email_verified_at`, `password`, `remember_token`, `created_at`, `updated_at`) VALUES
(1, 'Emilie Mante', 'kwiegand@example.com', '2023-03-02 17:43:37', '$2y$10$92IXUNpkjO0rOQ5byMi.Ye4oKoEa3Ro9llC/.og/at2.uheWG/igi', 'Y3FP2DroH6', '2023-03-02 17:43:37', '2023-03-02 17:43:37'),
(2, 'Reyna Stroman II', 'schuster.carlos@example.com', '2023-03-02 17:43:37', '$2y$10$92IXUNpkjO0rOQ5byMi.Ye4oKoEa3Ro9llC/.og/at2.uheWG/igi', '8tDlUix4oY', '2023-03-02 17:43:37', '2023-03-02 17:43:37'),
(3, 'Prof. Lauriane Yost I', 'greta69@example.com', '2023-02-02 17:43:37', '$2y$10$92IXUNpkjO0rOQ5byMi.Ye4oKoEa3Ro9llC/.og/at2.uheWG/igi', 'z6nEz8FkN6', '2023-02-02 17:43:37', '2023-02-02 17:43:37'),
(4, 'Zelma Yundt', 'ricardo.cartwright@example.com', '2023-02-02 17:43:37', '$2y$10$92IXUNpkjO0rOQ5byMi.Ye4oKoEa3Ro9llC/.og/at2.uheWG/igi', 'RsOsNYIogy', '2023-02-02 17:43:37', '2023-02-02 17:43:37'),
(5, 'Hayley Lebsack', 'elna.tillman@example.com', '2023-03-02 17:43:37', '$2y$10$92IXUNpkjO0rOQ5byMi.Ye4oKoEa3Ro9llC/.og/at2.uheWG/igi', '203SAe79eI', '2023-03-02 17:43:37', '2023-03-02 17:43:37'),
(6, 'Topmse Lebsack', 'topse.tillman@net.com', '2023-01-02 17:43:37', '$2y$10$92IXUNpkjO0rOQ5byMi.Ye4oKoEa3Ro9llC/.og/at2.uheWG/igi', '203SAe79eI', '2023-01-02 17:43:37', '2023-01-02 17:43:37');

Right now, you have only these few rows of dummy data. But you can take more rows in it. These data will help to draw graph between Total Registered Users according to Month wise.

You will see something like this after this test data insertion.

Create Graph Controller

Next, we need to create a controller file,

php artisan make:controller GraphController

It will create a file GraphController.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\User;
use Illuminate\Support\Facades\DB;
use Illuminate\View\View;

class GraphController extends Controller
{
    public function index(): View
    {
        $data['pieChart'] = User::select(DB::raw("COUNT(*) as count"), DB::raw("MONTHNAME(created_at) as month_name"))
            ->whereYear('created_at', date('Y'))
            ->groupBy('month_name')
            ->orderBy('count')
            ->get();

        return view('pie-chart', $data);
    }
}

Concept

Here, this is the concept by which you can setup data to be visible into graph.

User::select(DB::raw("COUNT(*) as count"), DB::raw("MONTHNAME(created_at) as month_name"))
    ->whereYear('created_at', date('Y'))
    ->groupBy('month_name')
    ->orderBy('count')
    ->get();

The date(‘Y’) returns the current year.

That’s why In test data, we have taken the year as 2023 so that we can get a pie chart on the behalf of sample data.

Note*: If your current year is different then you will not be able to see the pie chart view on output.

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,

<!doctype html>
<html lang="en">

<head>
    <title>Laravel 10 and Google Pie Chart Integration Tutorial</title>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

    <div class="container">

    </div>
    <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
    <script type="text/javascript">
        google.charts.load('current', {
            'packages': ['corechart']
        });
        google.charts.setOnLoadCallback(drawChart);

        function drawChart() {

            var data = google.visualization.arrayToDataTable([
                ['Month Name', 'Registered User Count'],

                @php
                    foreach ($pieChart as $d) {
                        echo "['" . $d->month_name . "', " . $d->count . '],';
                    }
                @endphp
            ]);

            var options = {
                title: 'Users Detail',
                is3D: false,
            };

            var chart = new google.visualization.PieChart(document.getElementById('pie-chart'));

            chart.draw(data, options);
        }
    </script>
</body>

Add Route

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

//...

use App\Http\Controllers\GraphController;

//...

Route::get('pie-chart', [GraphController::class, 'index']);

//...

Application Testing

Run this command into project terminal to start development server,

php artisan serve

URL: http://127.0.0.1:8000/pie-chart

Output

That’s it.
