Not really a visualisation tool, but I'm going to plug my dbus pcap parser
here - it's helped me analyse a number of silly problems of dbus
interactions between a number of applications:

It desperately needs a README, but you can slice and dice `busctl capture`
output with DBus filter specifications, and if you like dump the output as
json for further processing.
