OmniGraffle Pro 7.25.0 Multilingual | macOS | 73 mb

OmniGraffle Pro helps you draw beautiful diagrams, family trees, flow charts, org charts, layouts, and (mathematically speaking) any other directed or non-directed graphs. We've had people use Graffle to plan plotlines for a story, make an overview of an operating system, show the evolution of computers, and even show how diseases can spread in a closed population.
