CharGer is a conceptual graph editor intended to support research projects and education. Its current version is primarily an editor to create visual display of graphs. It is deliberately and explicitly a research tool meant for conceptual graph researchers to explore implementation issues in conceptual graph interfaces. Using the software will require some familiarity with conceptual graphs, including knowing about concepts and relations, type hierarchies and type/referent pairs. Knowing about actors will also be very helpful. For information about conceptual graphs, see the Web page: http://conceptualgraphs.org.
