What are the advantages and disadvantages of using JavaScript in the browser to copy PHPlot graphics to the clipboard?

To copy PHPlot graphics to the clipboard using JavaScript in the browser, the advantage is that it allows for easy implementation of a copy functionality without the need for server-side processing. However, the disadvantage is that it may not work consistently across all browsers and may require additional permissions from the user. 

// PHP code to generate PHPlot graph
require_once 'phplot.php';

$data = array(
  array('Jan', 10),
  array('Feb', 20),
  array('Mar', 15),
  array('Apr', 30),
);

$plot = new PHPlot(800, 600);
$plot->SetDataValues($data);
$plot->SetTitle('Sample PHPlot Graph');
$plot->SetXTitle('Month');
$plot->SetYTitle('Value');

$plot->DrawGraph();

// JavaScript code to copy graph to clipboard
echo '<button onclick="copyGraph()">Copy Graph</button>';
echo '<script>
function copyGraph() {
  var canvas = document.querySelector("canvas");
  canvas.toBlob(function(blob) {
    navigator.clipboard.write([new ClipboardItem({ "image/png": blob })]);
  });
}
</script>';
