How can conditional visibility of each graph be implemented in the code effectively?

To implement conditional visibility of each graph effectively, you can use PHP to dynamically generate the HTML code for each graph based on a condition. You can use an if statement to check the condition and only display the graph if the condition is met. This way, you can control the visibility of each graph based on specific criteria.

<?php
$showGraph1 = true;
$showGraph2 = false;

if ($showGraph1) {
    echo "<div id='graph1'>Graph 1 content here</div>";
}

if ($showGraph2) {
    echo "<div id='graph2'>Graph 2 content here</div>";
}
?>
