Flot
Introduction
This introduction is extracted from the Flot official website : http://code.google.com/p/flot/ :
"""Flot is a pure Javascript plotting library for jQuery. It produces graphical plots of arbitrary datasets on-the-fly client-side.
The focus is on simple usage (all settings are optional), attractive looks and interactive features like zooming and mouse tracking.
The plugin is known to work with Internet Explorer 6/7/8, Firefox 2.x+, Safari 3.0+, Opera 9.5+ and Konqueror 4.x+.[...]"""

<h1>Flot Examples</h1>
<div id="placeholder" style="width:600px;height:300px;"></div>
<p>Simple example. You don't need to specify much to get an
attractive look. Put in a placeholder, make sure you set its
dimensions (otherwise the plot library will barf) and call the
plot function with the data. The axes are automatically
scaled.</p>
<script id="source" language="javascript" type="text/javascript">
$(function () {
var d1 = [];
for (var i = 0; i < 14; i += 0.5)
d1.push([i, Math.sin(i)]);
var d2 = [[0, 3], [4, 8], [8, 5], [9, 13]];
// a null signifies separate line segments
var d3 = [[0, 12], [7, 12], null, [7, 2.5], [12, 2.5]];
$.plot($("#placeholder"), [ d1, d2, d3 ]);
});
