## What it is
Isomer is a small JavaScript library for drawing isometric graphics on HTML5 canvas. It provides simple primitives like prisms, pyramids, points, and colors to compose isometric scenes.

## Use cases
- draw isometric scenes on html5 canvas
- render 3d-looking cubes and shapes in the browser
- create isometric game graphics with javascript
- visualize isometric grids and diagrams on a web page

## When to choose
- you want a tiny, dependency-free library for isometric canvas drawing
- you need simple prism/pyramid primitives with color control
- you prefer a script-tag include over a heavy 3D engine

## When to avoid
- you need full 3D rendering, lighting, or camera control
- you need WebGL performance or textured 3D models
- you need a library with active recent development

## Facets
- artifact type: library
- maturity: maintenance
- function: graphics, animation
- domain: graphics, web-development, frontend
- platform: browser
- tags: isometric-graphics, html5-canvas, 3d-projection, drawing, game-development, javascript
