Data visualisation library that works on all browsers [closed]

Question

Please recommend a data visualisation library that meets the following requirements:
1. works on all popular browsers (including ios safari)
2. java compatible
3. open-source (preferable)

So far I have used BirdEye (a comprehensive open source information visualization and visual analytics library for Adobe Flex) http://code.google.com/p/birdeye/
Pros of BirdEye: open source
Cons of BirdEye: does not work on ios browsers (it is flash-based)

I don't want to write a native app for iOS. Hence, I need something like BirdEye which works on iOS as well.

The primary goal of that application is to draw graphs for strategy map.

I have worked on google visualization API. I found it easy to use and supports wide range of options. Also their site has good sample code so learning curve is smooth.

I had done it for iOS safari. But I think, its supported on all major browsers because it's a Javascript based library.
