What are some best practices for handling graphical data in PHP, particularly when dealing with complex mathematical functions like the Gaussian curve?

When handling graphical data in PHP, particularly when dealing with complex mathematical functions like the Gaussian curve, it is important to use a library like GD or Imagick to generate and manipulate images. These libraries provide functions to create graphs, plot data points, and apply mathematical functions to generate curves like the Gaussian curve. By utilizing these libraries, you can easily visualize complex data in a graphical format. 

// Example code using GD library to plot a Gaussian curve

// Create a blank image
$image = imagecreatetruecolor(800, 600);

// Set background color
$bg_color = imagecolorallocate($image, 255, 255, 255);
imagefill($image, 0, 0, $bg_color);

// Plot Gaussian curve
for ($x = 0; $x < 800; $x++) {
    $y = 300 * exp(-(($x - 400) ** 2) / (2 * 100 ** 2)); // Gaussian function
    imagesetpixel($image, $x, $y, imagecolorallocate($image, 0, 0, 0));
}

// Output image
header('Content-Type: image/png');
imagepng($image);

// Clean up
imagedestroy($image);
