Use case
Pareto Chart Maker workflow
Pareto Chart Maker is for quality issues and business priorities. It works with ranked issue categories and cumulative priority, adds automatic sorting, cumulative percent, and 80/20 reference, and keeps the preview, checks, and exports tied to the data you entered.
From input to export
- Start with the issues sample or paste your own CSV, Manual data.
- Sort the categories by contribution.
- Use the cumulative line to decide which few causes explain most of the total.
- Export Pareto chart, Priority note after the checks explain any remaining context or readability issues.
When to use
- Use Pareto Chart Maker when you need to turn small data into a clearer chart.
- It is a good fit for quality issues and business priorities.
- It works best when your data resembles ranked issue categories and cumulative priority.
When not to use
- Do not use this workflow for time series where order matters.
- Do not publish the result until title, unit, source, and export size have been reviewed.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
- Sort by count before reading the cumulative line.
- Use the Pareto table to confirm share and cumulative percent.
- Keep the 80 percent reference visible.
Input and method
- The parser normalizes rows into a browser-side table and never requires an account.
- Field detection classifies ranked issue categories and cumulative priority into number, date, category, or text fields.
- Categories are sorted by contribution and paired with a cumulative percentage line.
- The score combines data readiness, field mapping, chart fit, labels, accessibility, and pareto chart export readiness.
Checks before export
- Reading the cumulative line without checking which categories drive the total.
- Exporting before adding a clear title, unit, or source note.
- Ignoring the page limit: this workflow is not intended for time series where order matters.
- Treating the score as approval instead of reviewing the specific fixes.
Export options
- PNG and SVG exports use the current pareto 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 time series where order matters.
- Image-only chart recognition, cloud storage, and collaborative editing are not part of this version.
- Generated summaries should be reviewed before publication.
