Google Analytics Chart displays interactive graphs of your Google Analytics data, similar to the Google Analytics Dashboard.
In order to use GA Chart, you must have a Google Analytics account (free to create at http://www.google.com/analytics/ ) and an active report installed on a site. You are not required to use the Google Analytics module.
The main chart is a timeline of all visits to your site between "today" and when you started recording traffic data (or some other start date of your choice). The secondary charts show visitors data and browser usage by visits. There is also a summary of your site's usage statistics (visits, pageviews, pages/visit, bounce rate, average time on site, and percent of new visits) and a list of the top 25 pages visited on your site.
