tcpstat is very configurable and the output can be customized (for
gnuplot for example):
   http://www.frenchfries.net/paul/tcpstat/

In ports there's /usr/ports/net/ntop.  It is a "top" like display for
network interfaces.  There was another in /usr/ports/net (name I forget)
which displays nice graphs as well.  Have a look at
/usr/ports/net/README.html

AFAIK there isn't much in the FreeBSD base system (why should there,
that's what ports are for :), but if you must, you *could* try something
like 'netstat 10', for example.  With a bit of awking/greping, you can
produce output suitable for a program like gnuplot.

-Paul.
