Instaviz is graph sketching for your iPhone.

When you were young, the grown-ups used to catch you doodling little circles and lines on the back of your exercise books or paper napkins, instead of paying attention to what they said. They didn’t realize that you need to sketch things out, how they relate to other things, in order to get them into your head and other people’s heads.

Much later, you learnt the grown-up names for these sketches — mind maps, concept maps, semantic networks, flowcharts, social networks, genomic hierarchies, E-R diagrams... — but here we just call ’em graphs.

- Sketch out a rough shape. Instaviz magically transforms it into a neat ellipse, circle, rectangle, square, diamond or triangle.
- Sketch a link between two shapes. Instaviz quickly redraws the graph with the most pleasing layout.
- Scroll the graph by dragging with two fingers.
- Zoom in and out with the two-finger pinch.
- To edit the label, color or style of a shape or link, double-tap on it.
- To change the shape, sketch the new shape over the old one.
- To delete a shape or link, tap on it and shake the iPhone.
- To export the graph, double-tap on the graph background then choose Export Graph. You can export the graph to box.net, iDisk (MobileMe) or any WebDAV server, in DOT/GV and PDF formats.

Throw away the exercise books and paper napkins, Instaviz will figure out the graph for you. Brainstorm and conceptualize with Instaviz like you use pencil and paper, without a pesky user interface getting in your way.

- Instaviz is international! Localized for Dutch, English, French, German, Portuguese and Spanish.
- Instaviz uses Recog, a new shape recognition engine. Trained on over 2,500 sketches drawn by real users, Recog uses advanced fuzzy logic to recognize what you just sketched in a split second.
- Instaviz uses Graphviz as its automated graph layout engine. The industry standard for automated graph layout, Graphviz represents over 18 years of research work at AT&T and won two Apple Design Awards in 2004.
