Having the pie graphs on the host nodes does a good job of showing active nodes, which translates to active links when running only for localhost. When promiscuous mode is turned on and more complex link relationships can be observed, the current setup loses information about link volume. How to address that?

1. Add link nodes between host nodes, and put the pies on the link nodes rather than the host nodes?
2. Keep the pies on the host nodes, but split the link lines into up/down segments w/ different colors/weights/other distinguishing characteristics?
