Searching for Java library to build an app that interacts with data

I have a project where I should analyse data via cluster analysis. Basically the data should be visualised like this picture shows

Each d开发者_运维百科ataset - for example let it be people - is one horizontal row, where vertical lines showing the attributes like sex, age, and so on. Now if this data could be shown I also want to move the rows horizontal and also vertical a) via code and b) via drag & drop.

Do anybody know a good library for that?

Important

• Target is desktop application
• Expected datasets around 500
• Attributes for each data set around 60
• There is an app in Java/SWT already, so solutions in this direction would be preferred
• The OS is Win7 so C# or similar would be a stopgap
• I really like d3.js, and would prefer a similar lock & feel (but in 3D)

If somebody has recommendations for a library which helps to analyze the data, please step forward too!

Check What is the best open-source java charting library? and Libraries for pretty charts in SWT? for more info.

I did used JFreeChart with SWT (2 years ago). The code is quite horrible (you have to write tons of code), but it works and is directly renderable with SWT components (no need of SWT_AWT bridge).

EDIT

When I thought about it again, I realized, that you can use the JavaScript library through Browser widget. It's quite heavyweight solution, but it might work..

You can do this in d3 but it is a very involved process in which you need to deal with the ismoetric perspective and the rest. It shouldn't be terribly complicated but it will not be an out-of-the-box solution.
