1. A method, comprising: processing dialogs from a dialog system to identify paths through the dialog system, each of the dialogs having a corresponding identified path, wherein each of the dialogs comprises a user interaction with the dialog system; determining a first path of the identified paths having a usage less than a first predetermined value or a usage greater than a second predetermined value; generating a visual call flow representation of the identified paths of the dialog system, the visual call flow representation including nodes and edges connected to correspond to the identified paths; and displaying the first path in the visual call flow representation as a fading path if the first path is determined to have a usage less than the first predetermined value or as an enhanced path if the first path is determined to have a usage greater than the second predetermined value.
