Use case

Comparison Chart Maker workflow

Comparison Chart Maker is for product, vendor, and education comparisons. It works with options compared across multiple decision criteria, adds winner markers, difference percentages, and normalized metric notes, and keeps the preview, checks, and exports tied to the data you entered.

From input to export

  1. Start with the comparison sample or paste your own CSV, Manual data.
  2. Use consistent units before comparing options.
  3. Review the winner marker and caveats before using the result.
  4. Export Comparison chart, Decision note after the checks explain any remaining context or readability issues.

When to use

  • Use Comparison Chart Maker when you need to compare options across several criteria.
  • It is a good fit for product, vendor, and education comparisons.
  • It works best when your data resembles options compared across multiple decision criteria.

When not to use

  • Do not use this workflow for single-metric rankings where a bar chart is simpler.
  • Do not publish the result until title, unit, source, and export size have been reviewed.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

  • Map fields before reading the chart.
  • Choose a chart type from the preview controls.
  • Add title and source context before export.

Input and method

  • The parser normalizes rows into a browser-side table and never requires an account.
  • Field detection classifies options compared across multiple decision criteria into number, date, category, or text fields.
  • Multiple numeric criteria are rendered together so option tradeoffs are visible.
  • The score combines data readiness, field mapping, chart fit, labels, accessibility, and comparison chart export readiness.

Checks before export

  • Using Comparison Chart Maker with data that is better suited to single-metric rankings where a bar chart is simpler.
  • Exporting before adding a clear title, unit, or source note.
  • Ignoring the page limit: this workflow is not intended for single-metric rankings where a bar chart is simpler.
  • Treating the score as approval instead of reviewing the specific fixes.

Export options

  • PNG and SVG exports use the current comparison 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 single-metric rankings where a bar chart is simpler.
  • Image-only chart recognition, cloud storage, and collaborative editing are not part of this version.
  • Generated summaries should be reviewed before publication.
