I am a lover of Google Charts API and used it in some of my applications. For those who are new to this:
Google Charts API is a dynamic chart generation tool. Charts can be generated at by passing suitable parameters to the API call and are rendered as images.
There is a good amount of documentation available for developers, who wish to use this service.
Recent features that are added include:
- Adding Markers to the chart
- Concentric Pie Charts and controlling their orientation
- Data labels
- Margin Controls and much more…
