Organization of Graphics Objects
Graphics objects are the basic drawing elements used by MATLAB software
to display data. Each instance of an object is associated with a unique
identifier called a handle. Using this handle,
you can manipulate the characteristics (called object properties)
of an existing graphics object. You can also specify values for properties
when you create a graphics object.
These objects are organized into a hierarchy, as shown by the
following diagram.

The hierarchical nature of the Handle Graphics technology
is based on the interdependencies of the various graphics objects.
For example, to draw a line object, MATLAB needs an axes object
to orient and provide a frame of reference to the line. The axes,
in turn, needs a figure window to display the axes and its child objects.
