In one embodiment, a method includes: retrieving data relevant to a first screen of an electronic program guide; generating a graphical user interface using the retrieved data, in which: a first node identifies the first screen; second nodes identify second screens accessed after the first screen, each of the second nodes being positioned to one side of the first node; the first node is connected to each of the second nodes by connectors, each of the connectors pointing towards each of the second nodes and having a width proportional to a volume of navigation flow received by each of the second nodes from the first node; wherein at least one node comprises a visual indication indicating an average time spent by the users on an identified screen of the electronic program guide; and rendering the generated graphical user interface on a display screen of the computing device.
