What is OmniGraffle?

OmniGraffle is a diagramming and vector graphics application for macOS and iPadOS developed by The Omni Group, used to create flowcharts, org charts, wireframes, network diagrams, and other structured visual documents. It can import Microsoft Visio files (.vss, .vtx, .vsx) and saves documents in the .graffle format. Reusable shape libraries use the .gstencil extension.
