# Visual accessibility

Aim for legible hierarchy, high enough text contrast for intended audience, readable labels, sensible color use and sufficient whitespace. Important distinctions must not be encoded by color alone.

Charts should have direct labels, units, accessible captions/alt text where applicable, and distinguishable patterns if colors are reused. Diagrams should have clear direction arrows and source notes.

When static graphics will be posted online, recommend meaningful alt text when asked for publishing help. For screenshots and UI mockups, mark them as concepts rather than promises of keyboard or screen-reader operability; only real implementations can be functionally tested.
