@Hawkee Check out this charting library written in pure js. Using it for a personal project. It's quick, easy to use and offers a tremendous amount of features - not to mention FREE. http://www.highcharts.com/
Looks pretty nice. We're using Google Charts because they're easy to implement and require little to no overhead. These seem much more interactive though.
Yeah, they're not bad. There's quite a bit more code involved than the Google API but, it's not /too/ obtrusive. Haven't seen any slow down with them either. Being pure js, they're pretty responsive. Great documentation too!
