Use case

Chart Alt Text Generator workflow

Chart Alt Text Generator is for publishing charts on web pages and reports. It works with monthly revenue by channel, region, cost, orders, and target, adds data-aware summary, trend mention, and accessibility wording checks, and keeps the preview, checks, and exports tied to the data you entered.

From input to export

  1. Start with the revenue sample or paste your own Current chart, CSV data.
  2. Treat the score as a checklist, not a final approval.
  3. Apply the specific fixes before exporting or publishing.
  4. Export Alt text, Summary after the checks explain any remaining context or readability issues.

When to use

  • Use Chart Alt Text Generator when you need to find problems before a chart is published.
  • It is a good fit for publishing charts on web pages and reports.
  • It works best when your data resembles monthly revenue by channel, region, cost, orders, and target.

When not to use

  • Do not use this workflow for image-only chart interpretation in this version.
  • Do not publish the result until title, unit, source, and export size have been reviewed.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 monthly revenue by channel, region, cost, orders, and target 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 alt text 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 image-only chart interpretation in this version.
  • Treating the score as approval instead of reviewing the specific fixes.

Export options

  • PNG and SVG exports use the current alt text 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 image-only chart interpretation in this version.
  • Image-only chart recognition, cloud storage, and collaborative editing are not part of this version.
  • Generated summaries should be reviewed before publication.
