Hi, I'm currently wanting to develop a survey system that use asp.net with c#.

My problem now is for the create statistic and bar charts part, is the visual studio.net able to support dynamic graph and chart results show out.

Is the crystal report in vs.net useful in this situation?

Or I need to install extra software like dotnetcharting in order to do the dynamic graph and chart?

And, dotnetcharting is free?

Urgently need advice, help.....
