Caption

• The nodes are the applications, or the modules of the applications (if you use the option show-modules)

• One edge means that the node source import the node destination

• When there is a cycle the edge has a background color (the same color in all the cycle), and it label contains “Cycle X”

• The label of the edges contains the weight in parentheses

• If you use the options show-modules, each node has a background color. If two nodes are to the same application, they have the same background color.

• If a edge is dotted, every import between these two nodes is into a function
