## What it is
Go Graphics (gg) is a pure Go library for 2D rendering with a simple, Cairo-like API for drawing shapes, paths, text, and images. It supports saving output as PNG and is widely used, with nearly 5,000 stars and over 1,900 dependent packages.

## Use cases
- generate images programmatically in Go
- draw shapes and text onto a canvas
- create charts or diagrams as PNG files
- render 2D graphics without C dependencies
- annotate or composite existing images
- generate placeholder or thumbnail images

## When to choose
- you need simple 2D drawing in pure Go with no external dependencies
- you want an easy API for shapes, paths, text, and image compositing
- you need to programmatically generate PNG images

## When to avoid
- you need GPU-accelerated or real-time rendering
- you need 3D graphics or a full game engine
- you need advanced features like SVG output or complex filters

## Facets
- artifact type: library
- maturity: maintenance
- function: graphics, image-processing
- domain: graphics, developer-tools
- platform: go, cross-platform
- tags: 2d-graphics, rendering, canvas, png, drawing, pure-go
