Using the new Python API in flowd-0.9, it is very easy to write custom processing applications. Here are the results of a couple of hours of figuring out RRDtool's subleties: a small pair of scripts to chart NetFlow data (example results). Details on how to use these scripts are contained in this mailing list post.

The scripts currently summarise traffic by IP protocol, but this approach can be extended to plotting any pretty much any classification of traffic - reports by IP address, or by [IP address + TCP port] are easy to realise too.
