Parallel sets
Compare how categorical groups flow between two dimensions with weighted ribbons. Create a private, publication-ready parallel sets 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.

Multi-Variable Correlation & Flow Mechanics
Parallel sets visually represent multidimensional categorical data by showing how groups flow and split across different variables. Each vertical axis represents a distinct categorical dimension (such as demographics or product types). The weighted ribbons connecting these axes illustrate the frequency or proportion of observations shared between categories, making it easy to spot dominant paths and cross-tabulated breakdowns. All parallel sets rendering and flow calculations are processed entirely locally on your device, guaranteeing that your data is never uploaded to external servers.
Coordinate & Matrix Data Structure
Format input columns for parallel sets with explicit headers and numerical measurements. Verify that rows represent discrete categories or observations without unformatted symbol artifacts.
Sample Observation Matrix
| Class | Sex | Age | Survived | Count |
Correlation Traps & Analytical Guidelines
- Ensure sufficient visual distinction for parallel sets marks across standard and high-contrast viewports.
- Align text labels horizontally whenever possible to improve cognitive readability for parallel sets elements.
- Double-check scale boundaries and zero-anchors before exporting parallel sets presentation artwork.
- Data shape
- Source category, target category, and flow value columns
- Exports
- SVG, PNG, and Excel data; PowerPoint export is temporarily unavailable pending dependency review.
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
How does parallel sets differ from Sankey diagrams?
Parallel sets represent strict cross-tabulated categorical attributes across common axes, whereas Sankey diagrams represent arbitrary network flows.
