The Snag

Some encodings (area, angle) are decoded inaccurately; charts mislead.

The Move

Specify position and length encodings when requesting or reviewing charts.

The Cure

Choose visual encodings by perceptual accuracy to minimize misreading.

The Read

Position > length > angle > area — perceptual accuracy ranks encoding choices.
