Radial tidy tree generator

Radial tidy tree

Display hierarchical connections radiating from a center root node. Create a private, publication-ready radial tidy tree 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.

Data

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

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.

Hierarchical Structure & Parent-Child Nesting

A radial tree (or radial tidy tree) visualizes hierarchical parent-child relationships by mapping nodes into a 360-degree polar coordinate layout. The primary root node is anchored at the center, with subsequent generations branching outward in concentric circles. This structure efficiently distributes nodes across the canvas, making it particularly effective for visualizing large numbers of leaf nodes. All data parsing and rendering occurs locally on your machine, guaranteeing that your proprietary hierarchical data remains private and is never uploaded to external servers.

Tree Data Representation & Branching

Format input columns for radial tidy tree with explicit headers and numerical measurements. Verify that rows represent discrete nodes or geographic units without unformatted symbol artifacts.

Sample Node Hierarchy

| Node ID | Parent ID | Employee Count |

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

Data shape: Node id, parent id, and optional numeric 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

When should you use a radial tree instead of a linear one?

Radial trees conserve vertical space, making them excellent for broad, shallow hierarchies, while linear trees are better for deep, narrow structures.
