graphs can be constructed in a variety of ways. They can be built from vertices and edges directly in a symbolic form. They can come from built-in curated collections of theoretical or empirical graphs. Special graphs can be generated from parametric specifications. Random graphs following a variety of graph distributions allow one to build simulated internets or citation graphs, and test algorithms. Graphs can be fully specified by several types of matrices, or they can be imported from numerous supported file formats. Graphs can also be constructed in several steps by performing operations on graphs.
