## What it is
Circles is a lightweight, dependency-free JavaScript library that generates animated circular (ring) graphs in SVG. It renders a value ring with centered text and provides a simple API for creating and updating charts.

## Use cases
- display a percentage progress ring in SVG
- add animated circular stat charts to a dashboard
- show a radial gauge with a value in the center
- render circular progress indicators without chart library dependencies
- update a circle chart's value or radius dynamically

## When to choose
- you need simple circular/progress ring charts with minimal footprint
- you want zero dependencies and easy drop-in usage in plain HTML
- you need lightweight animated SVG charts rather than a full charting suite

## When to avoid
- you need bar, line, pie, or other chart types
- you need a full-featured charting library with axes, legends, and tooltips
- you need actively maintained software with recent releases

## Facets
- artifact type: library
- maturity: maintenance
- function: data-visualization, animation
- domain: data-visualization, frontend, web-development
- platform: browser
- tags: svg, circular-graphs, charts, no-dependencies, lightweight, javascript
