After searching for a template for Munin that was a little easier to use than the standard, I came across the Raven template by Simian Uprising. This worked great for Munin 1.2.x but does not work for version 2.0.x. So, rather than use the standard template or fix Raven, I created a new template called Modern.
This theme has been testing in the Chrome browser only but should work in all the majors.
Update 2014-10-18: The Theme can now be found on Git Hub: https://github.com/sjoudry/modern-munin
