This is goNetViz and it is written in golang. goNetViz visualizes your network traffic, either by reading a file or attaching to a network interface. The images below are based on the very same IP traffic. The differences are based on the number of bits per pixel. In the first image one bit is used per pixel. Then, in the second image, 3 bits of the payload are used per pixel. This is followed by 9 and 12 bits per pixel and finally 24 bits per pixel.
