Use case

Chart Color Accessibility Checker workflow

Chart Color Accessibility Checker is for making visuals easier to read. It works with survey answers, satisfaction counts, and response shares, adds contrast, color count, and red-green risk checks, and keeps the preview, checks, and exports tied to the data you entered.

From input to export

  1. Start with the survey sample or paste your own Chart colors data.
  2. Treat the score as a checklist, not a final approval.
  3. Apply the specific fixes before exporting or publishing.
  4. Export Accessibility notes after the checks explain any remaining context or readability issues.

When to use

  • Use Chart Color Accessibility Checker when you need to find problems before a chart is published.
  • It is a good fit for making visuals easier to read.
  • It works best when your data resembles survey answers, satisfaction counts, and response shares.

When not to use

  • Do not use this workflow for brand-only palette approval.
  • Do not publish the result until title, unit, source, and export size have been reviewed.
  • Use another chart preview when the recommendations explain a better fit.

Controls that matter

  • Use the score panel to identify the next fix.
  • Apply safe fixes such as source note, Top N, or chart switch.
  • Export the audit summary after review.

Input and method

  • The parser normalizes rows into a browser-side table and never requires an account.
  • Field detection classifies survey answers, satisfaction counts, and response shares into number, date, category, or text fields.
  • The chart logic checks audit fit against the detected fields and the current page task.
  • The score combines data readiness, field mapping, chart fit, labels, accessibility, and accessibility notes export readiness.

Checks before export

  • Exporting the score without acting on the listed issues.
  • Exporting before adding a clear title, unit, or source note.
  • Ignoring the page limit: this workflow is not intended for brand-only palette approval.
  • Treating the score as approval instead of reviewing the specific fixes.

Export options

  • PNG and SVG exports use the current accessibility notes preview and selected size.
  • Markdown and mini report exports include title, source note, detected fields, score, and fixes.
  • HTML, JSON config, clean CSV, and alt text are available from the secondary export panel when data is valid.

Output limits

  • Very large datasets should be summarized before using this browser-side tool.
  • Avoid this workflow for brand-only palette approval.
  • Image-only chart recognition, cloud storage, and collaborative editing are not part of this version.
  • Generated summaries should be reviewed before publication.
