## What it is
ProgressBar.js is a lightweight JavaScript library for creating responsive, animated progress bars using SVG paths. It ships with built-in shapes (Line, Circle, SemiCircle) and supports fully custom shapes with customizable animations.

## Use cases
- show an animated circular progress indicator on a dashboard
- create a slick loading bar for a web page
- render a semi-circle progress gauge with percentage text
- build a custom heart-shaped progress animation from an SVG path
- animate a file upload progress bar that works on mobile

## When to choose
- you need visually polished, animated SVG progress bars in vanilla JavaScript
- you want lightweight, dependency-free progress indicators that perform well on mobile
- you need custom-shaped progress bars from arbitrary vector paths

## When to avoid
- you need a full UI component framework with many widget types
- you want native HTML/CSS-only progress elements without SVG
- you need progress bars in a non-web environment like native mobile or desktop apps

## Facets
- artifact type: library
- maturity: maintenance
- function: animation, ui-components, frontend-framework
- domain: web-development, frontend, web-design
- platform: browser, cross-platform
- tags: progress-bar, svg, loading-indicator, javascript, nodejs
