Pages that contain many Backshift graphs are slow to render

My browser (Chrome v45.0.2454.101 on Fedora 22) crawls when trying to render performance reports that contain many Backshift graphs.

Interacting with the graphs (zooming, panning, etc) or scrolling down the page is also slow due to the large number of elements of the page.

This behavior can be reproduced by enabling the Backshift graphing provider, and rendering all of the graphs for 'opennms-jvm'.
