*
* Each graph implementation contains a static helper method for the construction of such a builder.
* For example class {@link DefaultDirectedGraph} contains method
* {@link DefaultDirectedGraph#createBuilder(Supplier)}.

*
* See {@link GraphTypeBuilder} for a builder of the actual graph instance.
