[Zoom]

I've got a web tool that I've written that helps my group debug things from our voluminous debug logs. I've done some nice HTML stuff, but I'd really like to draw some histograms and other simple images.

Most of my digging has led me to the GD libraries, which are not installed by default. If necessary, I'll do that, though it doesn't look fun.

Is there something simpler that I'm missing? Something that's already installed as part of Mac OS X Server (Snow Leopard)? I want to draw some straight lines of varying lengths and colors on an XY axis. Ideally, I'd like to have an imagemap, too, with tooltips and hot areas (clickable).

Thoughts?

OS X Server comes with PHP and GD library module by default. You can do all your basic drawing needs in PHP. Like so:

Code:
<?php
header ("Content-type: image/png");
$im = @imagecreatetruecolor(120, 20)
     or die("Cannot Initialize new GD image stream");
$line_color = imagecolorallocate($im, 233, 14, 91);
imageline($im, 0, 0, 120, 20, $line_color);
imagepng($im);
imagedestroy($im);
?>

Plenty of samples online, and it's very extensive. olePigeon's Yahtzee sig, for example. I did that with OS X's (Leopard) bundled PHP. Generates random dice and calculates your Yahtzee score for that hand. Would be pretty straight forward to adapt it to generating charts or whatever.
