WCAG AAAccessibility
WCAG 2.1 AA by default. Keyboard navigation, screen readers, pattern fills. Accessible by architecture, not afterthought.
Keyboard navigation
Navigate between data points with arrow keys. Tab to move between chart regions. Enter to activate tooltips. Escape to dismiss. Full keyboard support on every chart type.
Screen readers
Every chart includes ARIA roles, labels, and live regions. Screen readers announce chart type, data summary, individual values, and trends. Data tables are available as an alternative representation.
Pattern fills
Enable pattern fills to distinguish data series without relying on color alone. Stripes, dots, crosshatch - each series gets a unique pattern. Essential for color-blind users and printed output.
High contrast
All default color palettes meet WCAG AA contrast ratios against both light and dark backgrounds. Focus indicators are clearly visible. No information is conveyed by color alone.
Reduced motion
Respects prefers-reduced-motion. When enabled, charts render immediately without animation. Users who experience motion sickness see the same data with zero transitions.
