Quickly construct beautiful flow charts without drawing a thing — outline your ideas or data in the sidebar and let Automatic Layout do the rest. Visualize a vast concept or a simple organizational chart with an expansive, easy-to-use canvas.

Add the detail and polish you need, as you need it. Put your own style on UI elements or potted plants, create custom stencils for drag-and-drop creation later, and export your pixel-perfect document to the next person that needs it. The most advanced and easy to use wireframing and diagramming application.

Curves are beautiful and we've added even more in OmniGraffle 5 with the inclusion of Bézier lines. Add control points to your lines and then swing them around to create the sinuous lines you've always wanted.

Object styles (fill, stroke, image, shadow) now appear in a style tray at the bottom of the main window — there's no need to open a separate style inspector. Drag and drop style chits to other objects, to a group, or to a tool to instantly copy the style there.

Fire up the Outline view to quickly jot down thoughts — meanwhile, OmniGraffle is creating objects in the main window and automatically laying them out. If you like, move your outlines back and forth between OmniOutliner and OmniGraffle.

When you enter text information in the Outline view, the graphical objects that are created can be styled and restyled instantly the way you choose. OmniGraffle can associate a different style with each level in your outline, so all your level one items can be represented as blue diamonds, your level two items as purple horseshoes, and so on. You can even use OmniGraffle's outline styles as filters if you import OmniOutliner documents, by mapping styles to your OmniOutliner document structure. Create your own styles by laying out hierarchical objects in the document window and saving them as an outline style, or use our built-in styles.

Nearly all existing import and export options have been greatly refined and improved. A vector PICT export format is available: OmniGraffle can both copy as vector PICT and export to that format, so you can more easily copy and paste between OmniGraffle diagrams and popular applications such as Microsoft Word or PowerPoint. Hyperlinks are supported on export to PDF, as is exporting files with multiple canvases as a single, multiple-page PDF file. EPS export has a preview image associated with it. Finally, OmniOutliner support has been updated, with options to import multiple column information, numbering, notes, and more.

Styles are the visual elements that define the look of shapes in your document. And with OmniGraffle, you've got lots of options for creating beautiful antialiased diagrams that print exactly how they appear on your screen. Fill your shapes with solid or partially transparent colors (or drop in an image to be offset or tiled within your shape), render complex shadow schemes, define your shape's borders with any number of line types — or just copy a series of styles from another shape.

Smart guides help you lay out compelling documents in a flash. When you move a shape, distance markers pop up and tell you when your new shape is going to form an equally-spaced row or column with any other shapes. In addition to that, centerlines (or edge lines) draw when you are horizontally or vertically perfectly in line with another shape in your drawing, or the centerline of the canvas. When you're rotating or resizing a shape, markers tell you when your rotation/size matches that of other shapes. Instead of having to rely on a grid or your best guess, OmniGraffle tells you exactly how to create accurate and appealing diagrams.

Use subgraphs to expand and collapse segments of your diagram just like you can expand and collapse rows in outline view. Make a single diagram as simplified or as complex as you need.

Now it's even easier to work with PC using colleagues (until they see the light and switch to a Mac, that is). You can now open Microsoft Visio (VSD) files directly in OmniGraffle, along with Visio stencils (VSS) and Visio templates (VST).

Notes are a handy way to store arbitrary information about objects in a diagram. An object with a note displays the note in a tag when you rest the pointer over it for a moment; click the note inspector to view and edit the note. You can use rich text in notes, so they can be styled and include links to websites. Notes can be imported from or exported to OmniOutliner, and they also show up in presentation mode.

Use OmniGraffle Professional's ruler with automatic dimensioning when you're drawing something to scale, scale being the relationship between the size of the page and the size of the objects being drawn. You can set up a scale such as "1 in = 2 ft" or "100 px = 1 km" and OmniGraffle takes care of the rest — no need to do the math yourself.

OmniGraffle Professional supports exporting to the Scalable Vector Graphics (SVG) format which can display OmniGraffle documents beautifully at any size, whether you're viewing them on the screen of a mobile phone or on a large print banner.

Need to share your diagrams with an audience? With the Presentation Mode, you can show off all the great work you've created. Presentation Mode allows you to link multiple canvases together, and run a slide show that displays your documents full screen. Items on your canvases can be turned into clickable links that navigate throughout your OmniGraffle file — you can skip from canvas to canvas, forwards and backwards. Now you've got yet another powerful way to communicate your information visually using OmniGraffle.

To ensure your professional documents will print exactly as you've designed them, OmniGraffle Professional supports Apple's ColorSync technology to provide in depth proofing. ColorSync is the industry-standard color management technology that ensures color accuracy from capture to print or online display. It delivers powerful control over color matching at every step of the workflow process — ColorSync compensates for any deviations in the image-capturing systems of scanners, the display anomalies of monitors, and the color imaging components of printers and output devices.
