Would be good if user could click on pie chart segment and be taken to that data. This commit addresses this for the DX pie chart - needs to be tested on a larger dataset. Reopen issue #155.

Need to add links from pie chart segments to view the associated data.

[David Platten]

Links have now been added to the pie chart segments for both CT and DX (80c9ee9, 660e700). This issue is now fixed.
