Summary
In this chapter, we delved into the Visio object model, and looked at the hierarchy of the objects and collections.
We looked at the analytical parts of the Connectivity API, which enabled us to navigate connections and to retrieve surrounding containers and associated callouts.
We also used this knowledge to build a function that does some rudimentary checks of a diagram structure, and to list the steps in a process flow.
In the next chapter, we will look into the ShapeSheet and how to use the functions within it.
