Look Via Human Eye

Render and review as a human would: zoom to ~50% and scan for clarity.

Layout: no overlapping shapes; consistent spacing/grid; readable text size and contrast; legend if symbols/colors need explanation.

Flow: obvious direction; minimize crossing lines; stagger parallel edges; separate error/retry paths from happy path; decision diamonds readable (clear branches).

Hierarchy: group related shapes; similar nodes similar size; primary journey visually strongest.

Before sign-off: zoom-out test; “fresh eyes” readability; print/B&W sanity; trace each arrow without ambiguity.
