## What it is
A small JavaScript polyfill that adds external SVG spritemap support to browsers that lack it, such as older Safari, IE, and Edge versions. It lets developers reference symbols in external SVG files via <use> elements with graceful PNG fallbacks.

## Use cases
- use external svg spritemaps in all browsers
- make svg use elements work in internet explorer
- add icon sprite fallbacks for old browsers
- polyfill external svg symbol references in safari 6
- serve icons from a single svg file across legacy browsers

## When to choose
- you need external SVG spritemaps to work in legacy browsers like IE 6-11, old Safari, or Edge 12
- you maintain a site that must support very old browsers and uses SVG icon systems

## When to avoid
- you only target modern browsers, which support external SVG spritemaps natively
- you are starting a new project without legacy browser requirements

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components
- domain: web-development, frontend
- platform: browser
- tags: svg, spritemaps, icons, polyfill, internet-explorer, browser-compatibility
