The foregrounding of automatic layout in the key features of OG, and the pole position of a neat and symmetrical-looking org-chart in the OmniGraffle marketing gallery might well encourage exploration of OG as a quick generator of org-charts.

OG does provide a perfectly good environment for manually laying out and formatting tree diagrams and org-charts, but you won't get much help from the Graphviz engine which automatic layout is based on – Graphviz was really designed for other things.

(It doesn't support vertical stacking of the lowest level of the tree, introduces spurious asymmetries even into simpler trees, and often makes orthogonal links overlap in a way that creates ambiguities). See, for example, these other threads:
