Caption

• The nodes are applications, or (if you use the option “Show modules”) modules in the applications

• One edge means that the source node imports from the destination node

• Every edge of a cycle has the same background color and the label contains “Cycle X”

• The labels of the edges contain the weight in parentheses

• If you use the “Show modules” option, each node will have a background color. If two nodes are from the same application, they will have the same background color.

• If an edge is dotted, every import in the source happens at runtime, whithin the body of a function or method
