From the developer:
AirPort Flow is a small utility to monitor the transfer rates on an AirPort Extreme. The rates are polled from the AirPort Extreme by SNMP. The top graph shows the incoming TCP traffic to the router and the lower one shows the outgoing TCP traffic from the router on a given interface.
