What considerations should be made when choosing a PHP library for generating charts based on user input data?

When choosing a PHP library for generating charts based on user input data, it is important to consider factors such as ease of use, customization options, compatibility with different chart types, and support for real-time data updates. Additionally, the library should have good documentation and a strong community for any troubleshooting needs.

// Make sure to include the Chart.js library in your project

// Sample user input data
$data = [10, 20, 30, 40, 50];

// Create a new chart instance
echo '<canvas id="myChart" width="400" height="400"></canvas>';
echo '<script>';
echo 'var ctx = document.getElementById("myChart").getContext("2d");';
echo 'var myChart = new Chart(ctx, {';
echo 'type: "bar",';
echo 'data: {';
echo 'labels: ["January", "February", "March", "April", "May"],';
echo 'datasets: [{';
echo 'label: "User Data",';
echo 'data: ' . json_encode($data) . ',';
echo 'backgroundColor: "rgba(255, 99, 132, 0.2)",';
echo 'borderColor: "rgba(255, 99, 132, 1)",';
echo 'borderWidth: 1';
echo '}]';
echo '},';
echo 'options: {';
echo 'scales: {';
echo 'yAxes: [{';
echo 'ticks: {';
