Next step, open your web.php file and add the following routes into your file:

routes/web.php

Route::get('graph', 'GraphPdfController@index');
Route::get('download', 'GraphPdfController@download')->name('download');

The first route will show graph on web page and the second one is download the pdf file.

Step 5: Create Controller by Command

Next open your command prompt and run the following command to create a controller by artisan:

php artisan make:controller GraphPdfController

This command will create a controller that name GraphPdfController.php.

Next go to app/Http/Controllers and open GraphPdfController.php. Then update the following methods into your controller file:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use mikehaertl\wkhtmlto\Pdf;

class GraphPdfController extends Controller
{
/**
* Write code on Construct
*
* @return \Illuminate\Http\Response
*/
public function index()
{
return view('graph');
}

/**
* Write code on Construct
*
* @return \Illuminate\Http\Response
*/
public function download()
{
$render = view('chart')->render();

$pdf = new Pdf;
$pdf->addPage($render);
$pdf->setOptions(['javascript-delay' => 5000]);
$pdf->saveAs(public_path('report.pdf'));

return response()->download(public_path('report.pdf'));
}
}

In this controller, you have update two methods. First index() method will load the web page and display the graph with data. And the downlaod() method will download the pdf file.

<script src="https://www.google.com/jsapi"></script>
<style>
.pie-chart {
width: 600px;
height: 400px;
margin: 0 auto;
}
.text-center{

</style>
</head>
<body>
