Pareto chart generator

Pareto chart

Rank categories by impact and show the cumulative share of the total. Create a private, publication-ready pareto chart directly in your browser without transmitting sensitive rows off-device. Data is processed locally on your hardware with zero server uploads, enabling instant export to SVG, PNG, and Excel data.

Edit the data, then export.

Everything runs in your browser. Your data is not uploaded.

Data

Paste tab-separated data from Excel or edit the cells directly.

Paste or import table data

Paste a header row, or choose a local CSV/TSV file. Files are read in this browser and capped at 500 rows.

SVG, PNG, and Excel exports are generated locally in this browser. PowerPoint export is temporarily unavailable while its dependency path is reviewed for a high-severity image parser advisory.

Visual Encoding & Comparative Anatomy

A Pareto chart combines a descending bar chart with an ascending cumulative percentage line to identify the largest factors contributing to a total effect. The bars represent individual category values ordered from largest to smallest along the primary axis, while the line tracks the cumulative total percentage across categories on a secondary axis. This dual-axis visualization helps isolate the “vital few” drivers from the “trivial many.” Trendalyzer renders this chart entirely in your local browser, guaranteeing that your data is never uploaded to external servers.

Input Format & Required Columns

Format input columns for pareto chart with explicit headers and numerical measurements. Verify that rows represent discrete categories or observations without unformatted symbol artifacts.

Best Practices for Category Comparison

Ensure sufficient visual distinction for pareto chart marks across standard and high-contrast viewports.
Align text labels horizontally whenever possible to improve cognitive readability for pareto chart elements.
Double-check scale boundaries and zero-anchors before exporting pareto chart presentation artwork.

Data shape: Category and numeric value columns

How it works

You edit a table in this page. The renderer draws an SVG from those rows in your browser, then you can download SVG, PNG, or Excel data. The table is not uploaded to any external processing server.

Frequently asked questions

What is the 80/20 rule in a Pareto chart?

It posits that roughly 80% of total problems or outcomes stem from just 20% of specific causes; fixing those top few causes yields the highest ROI.
