Google Charts API
December 7th, 2007Outsource your charting to Google! Yesterday I discussed my initial experiences with the Flot charting library. Today, I’m going to give you a brief introduction to the excellent new Google Charting API.How it works, simply embed an image tag in your source that references the google chart API location followed by a set of parameters specifying the actual chart. Google then renders the chart as a PNG that can be displayed in the browser.Features:
