What are the limitations of using GD functions for creating complex graphics like family trees with multiple levels?

The limitations of using GD functions for creating complex graphics like family trees with multiple levels include the lack of built-in support for easily managing multiple levels of hierarchy and connections between nodes. To solve this issue, you can consider using more advanced libraries or tools specifically designed for creating complex graphics, such as GraphViz or D3.js.

// Example using GraphViz to create a family tree with multiple levels
require_once 'vendor/autoload.php';

use Graphp\GraphViz\GraphViz;
use Graphp\GraphViz\GraphVizException;

$graph = new Fhaculty\Graph\Graph();

$parent = $graph->createVertex('Parent');
$child1 = $graph->createVertex('Child 1');
$child2 = $graph->createVertex('Child 2');

$graph->createEdgeDirected($parent, $child1);
$graph->createEdgeDirected($parent, $child2);

$graphviz = new GraphViz();
$graphviz->display($graph);
