A simple Graph Theory toy. Connect points on a graph together with other points. Move them around to find isomorphic graphs. Can you find a way to make none of the lines cross? With a custom graph, you can: ‣ Double-tap one of the colored points to delete it. ‣ Add a new point with the + button up top. ‣ Tap-and-hold on a point to select it, then tap any other point to add or remove a line between the two. ‣ Slide and glide the points around to find new ways to view your graph.
