The MTM dashboards can be toggled between static or interactive graphs subject to your preference from the User Preferences Menu.
The Default chart style is static which provides for a faster graph loading experience and better data included on the "pie" or "dounut" charts.
nvd3 is a good interactive view for most pages as it allows interactivity of the mouse with data points on the graphs.
flot is a balanced view of performance and interactivity with the graphs on the pages.
The graph mode can be toggled at any time and the changes will be in effect immediately.
