Radial area chart
Compare a multi-dimensional profile around a radial set of axes. Create a private, publication-ready radial area 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 radial area chart plots quantitative values as a filled polygon mapped onto polar coordinates. Each category is distributed equally around the circle as an angular wedge or axis, and the metric’s magnitude dictates the distance from the center origin. This is particularly useful for exposing asymmetrical performance profiles or cyclical patterns. Trendalyzer renders this chart completely locally in your browser, guaranteeing that your raw categorical data and values are never uploaded to any external server.
Input Format & Required Columns
Format input columns for radial area chart with explicit headers and numerical measurements. Verify that rows represent discrete categories or observations without unformatted symbol artifacts.
Example Comparison Table
| Dimension | Value | Maximum |
Best Practices for Category Comparison
- Ensure sufficient visual distinction for radial area chart marks across standard and high-contrast viewports.
- Align text labels horizontally whenever possible to improve cognitive readability for radial area chart elements.
- Double-check scale boundaries and zero-anchors before exporting radial area chart presentation artwork.
- Data shape
- Category, value, and maximum 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.
