## What it is
A JavaScript library that adds panning and zooming to SVG images embedded in HTML documents, via mouse scroll, double-click, touch gestures, or programmatic API calls. It supports inline SVGs as well as SVGs loaded through object or embed elements, with optional on-screen zoom controls and onPan/onZoom event hooks.

## Use cases
- add pan and zoom to an inline SVG diagram in a web page
- make an SVG map pannable and zoomable with mouse wheel and touch
- control SVG zoom programmatically from JavaScript
- add on-screen zoom controls to an embedded SVG
- listen for pan and zoom events on an SVG viewer
- enable pinch-to-zoom on SVGs for mobile users

## When to choose
- you need simple, dependency-free pan/zoom for SVG content in the browser
- you want both mouse and touch support with a small JavaScript API
- you need cross-browser support for inline and embedded SVGs

## When to avoid
- you need pan/zoom for raster images or canvas rather than SVG
- you need advanced features like rotation, deep-zoom tiling, or WebGL rendering
- you are building a full-featured map application where a mapping library fits better

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, animation
