## What it is
GeoPattern is a JavaScript library that deterministically generates tiling SVG geometric patterns from an input string, seeded via SHA-1 hashing. It works in the browser (with an optional jQuery plugin) and in Node.js, and is a port of the Ruby geo_pattern library originally used for GitHub Guides backgrounds.

## Use cases
- generate unique svg background patterns from a string
- create deterministic geometric avatars or header images
- add generative svg backgrounds to a website
- generate patterned placeholder backgrounds for cards or profiles
- port of geo_pattern for javascript projects

## When to choose
- you need lightweight, dependency-free SVG pattern generation in JavaScript
- you want the same input string to always produce the same pattern
- you need patterns that work both in the browser and Node.js

## When to avoid
- you need raster image output like PNG or JPEG
- you need animated or interactive patterns rather than static tiling SVGs
- you need actively developed features; the latest release dates to 2021
