8.3. Call graph layout

The call graph provides you with a visual representation of your code hierarchy, laying out each function according to where it is called and using arrows to connect calling functions. The direction of the arrow indicates which function was the calling function. An arrow pointing to a function tells you that function is the callee and the function from which the line originates is the calling function. This section describes the layout of the call graph in more depth, providing a quick overview of how the hierarchy is built and what the bullets to the right and left of the call graph's functions represent.
