GraphNview is an open source tool that allows you to create and display graphs with extreme simplicity. It also has an integrated development environment to generate the animation of a graph. This environment includes: an ActiveX integrated control for viewing graphs, a set of simple commands to create graphs, create animations graphs and edit the information in nodes and arcs; an immediate command editor; a command interpreter with syntax checking. GrphNview uses the control chart GraphNup which is installed during the program setup. Limitations: GraphNview use the freeware GraphNup ActiveX control that added a small text (about the author's Web site) at the bottom and the top of each graph. You can contact the author by e-mail to ask information about the GraphNup control version without these limitations.
