Specific chart or graph

I need to create some specific chart or graph on WEB (Please see attachment). I found http://visjs.org/examples/graph2d/11_barsSideBySideGroups.html, which seems to be best solution. But there is no GWT wrapper. Can you recommend some good solution or tool to me?

Thanks,

David
