My client has requested data to be presented in a graphical format on the iPhone (a pie chart or something similar). I am wondering how others have handled this – A.) deliver the raw data to the phone and somehow build the chart on the phone, or B.) have the back-end services build the chart and deliver it (png format) to the phone?
Thanks for any advice.
Another alternative is to use the Google ChartAPI:
