## What it is
A d3.js-based JavaScript library that renders ThoughtWorks-style technology radar visualizations (quadrants and rings) as an SVG in the browser. It powers Zalando's public Tech Radar and can be embedded in any static page.

## Use cases
- publish a tech radar for my engineering organization
- visualize which technologies to adopt, trial, assess, or hold
- embed a technology radar chart on a static website
- create a ThoughtWorks-style radar with custom quadrants and rings
- track and communicate technology choices across teams

## When to choose
- you want a simple, embeddable radar visualization on a static page
- you like the Zalando/ThoughtWorks radar format with quadrants and rings
- you need a lightweight d3-based chart with automatic entry positioning

## When to avoid
- you need a full radar management platform with editing UI or backend
- you want interactive data entry or CMS integration out of the box
- you need charts other than a technology radar

## Facets
- artifact type: library
- maturity: active
- function: data-visualization, charts, documentation
- domain: developer-tools, data-visualization, documentation
- platform: browser
- tags: tech-radar, d3js, svg, static-site, technology-assessment, web-server, javascript
