## What it is
A JavaScript library that adds pan and zoom interactions to DOM elements and SVG scenes. It is extensible, mobile friendly, and emits transformation events for custom behavior.

## Use cases
- add pan and zoom to an SVG diagram
- make a DOM subtree draggable and zoomable
- build an interactive scene viewer in the browser
- support pinch-to-zoom on mobile web pages
- listen to pan and zoom transform events
- create a zoomable graph or map visualization

## When to choose
- you need lightweight pan/zoom for DOM or SVG content
- you want mobile touch support out of the box
- you need event hooks for transformation changes

## When to avoid
- you need canvas or WebGL-based zooming
- you need full-featured map tile interactions
- your framework already provides built-in pan/zoom components

## Facets
- artifact type: library
- maturity: stable
- function: animation, ui-components
- domain: web-development, frontend, graphics
- platform: browser
- tags: pan-and-zoom, svg, dom, transform, touch-support, javascript
