Open source library/framework for building dashboard (bar,line,pie,etc) [closed]

Question

I have done POC with highcharts and works fine and looks great.

I am looking for better open source library/framework using which i can develop my dashboard showing different graphs.

The UI framework must handle the real time data (like Ajax calls or REST).

Any helpful suggestion appreciated.

D3 (Data-Driven Documents) is excellent if you have a bit of time to learn it.
