Google Charts
Lifehacker had a post about Google’s new charting API. It’s pretty slick, you can use it to create on0the-fly, free charts for your website (of course there are limits to free usage). They have an nice API that is easy to understand and (at first look) seems easy to use. Check it out at Google’s Code API.
