By default, the yFiles library already offers various possibilities for writing a graph to different file formats. Table 9.2, “Supported file formats” lists the supported graph exchange file formats. The recommended file format, GraphML, is listed topmost. It offers the best mixture of robustness, compatibility, and flexibility.
