Radial stacked bar chart generator

Radial stacked bar chart

Compare category totals around a circle while preserving each total's component breakdown. Create a private, publication-ready radial stacked bar 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.

Part-to-Whole Composition Mechanics

A radial stacked bar chart projects multi-part stacked bars along concentric circular tracks, combining a compact circular layout with categorical compositional breakdown. It allows you to visualize total values across different categories while simultaneously displaying the sub-components that make up each total. All rendering and data processing happens entirely locally within your browser, guaranteeing that your sensitive datasets are never uploaded to external servers.

Categorical Proportions & Table Structure

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

Segment Allocation Guidelines & Pitfalls

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

Data shape: Category plus one numeric column per component
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

When should radial stacked bars be avoided?

Avoid when precise value comparisons are needed, as circular distortion makes measuring upper stacked segments challenging.
