What a pareto chart is
A Pareto chart ranks causes by frequency as descending bars, with a cumulative percentage line across the top. Where that line crosses 80% marks the vital few causes worth fixing first.
When to use one
- Choosing which defect or complaint category to attack first
- Demonstrating that a handful of causes drive most of the failures
- Showing before-and-after evidence that an intervention worked
The data format
Optional 'effect, <metric>' for the title. Then Cause, count — sorted automatically.
Paste rows like this — copy the example straight into the builder to see it render:
effect, Customer complaints Scratches, 48 Misalignment, 27 Wrong label, 15 Dent, 9 Color off, 6 Other, 4
How to make one
- Paste your data into the Studio, or upload a CSV or XLSX file.
- Set your colours — by hand, from pasted brand hex codes, or extracted from your logo.
- Generate and export as PNG or SVG for your deck or report.
One thing people get wrong. Rank by cost or time where you can, not just by count. Fifty trivial defects can rank above three that are actually expensive.
Why it runs in your browser
Charts are parsed and drawn entirely on your own device. No rows, files or logos are uploaded, so a pareto chart built from confidential project or process data never touches a server. You can verify it: open your browser's network tab while you generate one.
