Use case

Pie Chart Maker workflow

Pie Chart Maker is for small part-to-whole shares. It works with survey answers, satisfaction counts, and response shares, adds slice warnings, Other grouping guidance, and bar chart fallback, 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 CSV, Manual data.
  2. Keep the slice count small enough to label directly.
  3. Switch to a bar chart if the shares are too close to compare.
  4. Export Pie chart, PNG, SVG after the checks explain any remaining context or readability issues.

When to use

  • Use Pie Chart Maker when you need to summarize a small part-to-whole split.
  • It is a good fit for small part-to-whole shares.
  • It works best when your data resembles survey answers, satisfaction counts, and response shares.

When not to use

  • Do not use this workflow for more than seven slices or precise comparisons.
  • Do not publish the result until title, unit, source, and export size have been reviewed.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

  • Keep slices limited.
  • Use Top N to group smaller categories outside the preview.
  • Show percent labels only when the total is meaningful.

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 pie fit against the detected fields and the current page task.
  • The score combines data readiness, field mapping, chart fit, labels, accessibility, and pie chart export readiness.

Checks before export

  • Using Pie Chart Maker with data that is better suited to more than seven slices or precise comparisons.
  • Exporting before adding a clear title, unit, or source note.
  • Ignoring the page limit: this workflow is not intended for more than seven slices or precise comparisons.
  • Treating the score as approval instead of reviewing the specific fixes.

Export options

  • PNG and SVG exports use the current pie chart 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 more than seven slices or precise comparisons.
  • Image-only chart recognition, cloud storage, and collaborative editing are not part of this version.
  • Generated summaries should be reviewed before publication.
