Classes without elements

In this example, we specify only one class, and this class with its direct dependencies will be rendered in graph, without constants, properties and methods.

<?php
use Bartlett\GraphUml\ClassDiagramBuilder;
use Bartlett\GraphUml\Generator\GraphVizGenerator;

use Graphp\Graph\Graph;
use Graphp\GraphViz\GraphViz;

$options = [
    'label_format' => 'record',
    'show_constants' => false,
    'show_properties' => false,
    'show_methods' => false,
];

$builder->createVertexClass(ClassDiagramBuilder::class);

// show UML diagram statements
echo $generator->createScript($graph);

// default format is PNG, change it to SVG
$generator->setFormat('svg');

// generate binary image file
$target = $generator->createImageFile($graph);
echo (empty($target) ? 'no' : $target) . ' file generated' . PHP_EOL;

Will output this graph statements.

And image file generated look like :
