In this recent post to the Duckout blog, they show you how to hook your PHP-based (and database driven) application into the Google Charting API for chart/graph generation.
I think, whenever we see a chart in a magazine, in books or applications our brain say’s to us Yeepie!!! Don’t read these stupid texts or tables! Just look at the green or yellow line and hope that they are above the other lines or hope that your opinion is the biggest part of the pie. This saves us a lot of work and in my opinion we should concentrate on drawing beautiful colorized pie charts, instead of writing long boring articles. But the question is: How do I draw these beautiful colorized pie charts? The simple answer is: you don’t have to, because google will draw them for you and you just have to tell them what to draw via the google charts api.
