node_figures_hierarchy [GMF Samples And Tutorials]

The hierarchy created by GMF is not easy to apprehend in the generated code.

The section below shows the association between the editparts and the figures.

This can be useful to understand how to correct default border widths for example when you want your figure to use the maximum surface available.
