A class of graphs is hereditary if it is closed under taking induced subgraphs. Classes associated with graph representations have "composition sequences" and we show that this concept is equivalent to a notion of "amalgamation" which generalizes disjoint union of graphs. We also discuss how general

A hereditary property of graphs is a class of graphs which is closed under taking induced subgraphs. For a hereditary property \(\mathscr{P}\), let \(\mathscr{P}_{n}\) denote the set of \(\mathscr{P}\) graphs on \(n\) labelled vertices. Clearly we have \(0 \leqslant\left|\mathscr{P}_{n}\right| \leqs
