Ember vs Struts in highcharts

This is a very generic question which I am posting here, hoping to throw light on a few aspects of ember. I have an app where we show a lot of reports for which we internally use highcharts. Our application is built over struts and we typically:

-fetch data from server via struts action class -forward to a jsp -render the chart using highcharts (with javascript)

Now we are planning on migrating our app from struts to ember. However, I am not sure on the advantages ember has to offer w.r.t highcharts or rather charting in general. Will the advantage be seen only in the case of live charts and interactive charts? Can somebody please elaborate a little more on what I am missing?
