## What it is
Leon Sans is a geometric sans-serif typeface generated entirely with code, exposing glyph drawing-point coordinates so developers can dynamically change font weight and create custom animations, effects, and shapes on HTML5 Canvas. It ships as a JavaScript library for use in web pages.

## Use cases
- render animated text drawing effects on canvas
- dynamically change font weight in the browser
- create generative typography animations for a website
- draw text with custom shapes and effects like wave or metaball
- use a code-generated geometric sans-serif font in web projects

## When to choose
- you need programmatic control over glyph geometry for text animations
- you want a geometric sans-serif font with dynamic weight on HTML5 Canvas
- you are building creative-coding or generative-design web experiences with animated type

## When to avoid
- you just need a standard static font file for documents or print
- you need extensive multilingual or non-Latin script support
- you require a general-purpose text rendering engine beyond canvas-based effects

## Facets
- artifact type: library
- maturity: maintenance
- function: animation, graphics, ui-components
- domain: web-development, frontend, graphics
- platform: browser
- tags: typeface, font, canvas, creative-coding, generative-design, sans-serif, typography, javascript, web
