WiFi Graph 0.3 RC3
"WiFi Graph lets you spot neighboring Wireless LAN Access Points and their connectivity. With proprietary scanning technology, Access Point information is updated every second so you can always rely on it. IT security professionals can also use our XML-based logs to analyze the invisible network. As WiFi Graph is still in early development stage, only limited devices are supported. For details, please see the Supported Devices section or go to the Options page inside the application."
