Plot the structure of your structure.

Make a nice visualization of the contents of your structure. Even if it contains some substructures.

If you use structures, you know that they might start growing as weed while working on it.
For documentation purposes or just to FIND the stuff inside, it may be nice to have a plot of your structure's plot.
Starting from the root level, it iteratively goes through your structure and reads the hierarchy. Then it will plot a nice overview of the contents and hierarchy of your structure.
