Instaviz is graph sketching for your iPhone. Instaviz turns roughly sketched shapes and lines into aesthetically pleasing graphs, great for drawing concept maps and flowcharts, or just simple note-taking and brainstorming. Instaviz features two functions new to the iPhone platform: advanced shape recognition and automated graph layout. The user sketches a rough shape and Instaviz recognizes an ellipse, circle, rectangle, square or diamond in a split second. He sketches a link between two shapes and Instaviz quickly redraws the whole graph with the best layout. The user interface doesn’t get in the way of the brainstorming process, and the user doesn’t have to fuss with the layout since it is automated.
