Accessible Chart Alternatives

Charts need takeaway titles, text summaries, redundant encodings, and data-table alternatives; Canvas or SVG alone is not automatically accessible.

Data visualization is non-text and often interactive content. It must give equivalent conclusions and data paths to people who cannot see the chart, distinguish colors, use a mouse, or read it at default size.

Visualization Transform Provenance

Charts must record filter, aggregate, bin, timeUnit, join, missing-value, and sorting logic; otherwise users cannot audit why the chart looks the way it does.

Data-visualization trust comes not only from graphics but also from an explainable transform chain. Every aggregation, filter, and derived field should be traceable.
