From the developer:
iNetMonitor is an utility for the up- and download speed measurements on your Mac. It draws a histogram chart for the better visual network activity monitoring and calculates the current traffic speed updated every second. It could be useful when you want to check up your overall downloading rate, etc.
It can draw the chart directly on Dock icon or on the pushpinnable transparent resizable window on the Desktop.
