Diagrams are basic to the way people think, and we create them all the time without even realizing it. Whatever your profession or interests, chances are you've occasionally sketched out some ideas on a piece of graph paper or the back of a napkin.

OmniGraffle is the tool to help you organize your thoughts visually, document them beautifully, and communicate them to the world. More than just a silly name, OmniGraffle is a powerful, yet easy to use diagramming and drawing tool.

OmniGraffle can help you make amazing graphic documents quickly by keeping lines connected to shapes even when they're moved, providing stencils full of common symbols for you to drag and drop, and magically organizing diagrams with just one click. Create flow charts, org charts, network diagrams, family trees, project processes, office layouts - or anything else that can be represented by symbols and lines.
