http://www.highcharts.com/ - excellent integration and nice looking (free for non-commercial)
http://www.jqplot.com/ - open source, nice looking as well (free as in beer)
http://g.raphaeljs.com/ - another open source, well maintained
http://www.flotcharts.org/ - built specifically for JQuery (if that is what you are using)
Basically, take a look at these and others, find one that looks good and will easily plug in to your existing architecture and roll.
