1.5. Program Dependency Tree

The program dependency tree produced by Validators #1 and #2 shows program and variable
dependencies by displaying them in a tree hierarchy. The top level nodes in the tree give the programs
from the application. These expand to list the variables used by a program, and these in turn expand
to list the programs that use a variable. The icons are used for the tree nodes are assigned unique
colours and shapes, and have the following meanings as detailed below.

Green Round Icon

This node represents a program that has no shared variables, and expands to display only variables
that are not shared.

Red Round Icon

This node represents a program that has one or more shared variables, and expands to display both
shared and non-shared variable node types.

Green Square Icon

The node represents a variable that is not shared and expands to display only one program name.

Red Square Icon

The node represents a variable that is shared, and expands to display the names of the programs that
share it.
