Fix IE spacing for pie charts

The svg pie charts are being mis-aligned in IE because ID doesnt
correctly process the height and width attributes on an svg element
Using a viewBox resolves the issue and doesnt appear to cause any
side effects in other browsers. Note that the IE charts will scale
slightly as the browser window changes. Chrome and FF do not
exhibit this because they strictly apply the height and width
