How would you chart this in Excel for your executive dashboard?

An Excel forum user posted the following question.  I wanted to see how my readers would answer the following question.  Tomorrow I will post my solution (although I am sure it is not the best).  Please let me know you solution by posting a comment below.  So read on and come back tomorrow.

Here is the question that was posted:

 

Presenting Metrics Data

Trying to find the best way to display some metrics and am coming up with a blank as I need to provide business metrics data for number of calls data and preferably with Excel 2010.
Initial thought was to create a line graph with points and hyperlink the points to the sub-topics but can’t figure out how to do that, then I thought about a bar graph with different layers to it as to each sub-topic with no such luck.
Example below:
Specific Administration is the overall topic with a total of 417 for all other categories with “Add/Edit Contacts, Policy, Proctor Password, Request to Change Data” all falling under Specific Administration.
Then Navigation falls under Add/Edit Contacts, and General, Refer to XYZ, Refer to XY all falling under Policy and of the 381 stats for Policy is broken down by those and so I need to put that information with the sub-topic but not all sub-topics will have a sub-topic layer 2

Here is the sample the user provided
