IE cannot render charts with jquery 2.1

[yutannihilation]

IE users can't see the graph generated by metricsgraphics at all. In case you are a non-Windows user, here is a screenshot I took with my IE11:

Meanwhile, the official site [http://metricsgraphicsjs.org/] works perfectly fine with IE. One of the differences is the version of jquery; They uses 1.11.1 and we use 2.1.X in this metricsgraphics package.

I did bower install jquery#1.11.1 in metricsgraphics as an experiment, and then I saw charts were drawn correctly. It seems better to downgrade jquery, if you care about IE :)
