Another interesting Web 2.0 API. Google provides charting API calls for public to graphically display data. Now that I have successfully implemented Yahoo Query Language in the Pipes and aggregated some numbers, it is time to do something about the graphical part, as well.
My next target will be to utilize Google Chart API to display market prices over a period of time. The prices would come from official sources, be aggregated through Yahoo Pipes, and then displayed graphically through Google Charts.
