## What it is
nomnoml is a JavaScript library and tool for rendering UML diagrams from a compact text syntax, producing SVG or canvas output. It ships as an npm library, a CLI, and a client-side web editor with live preview.

## Use cases
- draw UML class diagrams from text
- render diagrams as SVG in Node.js
- embed diagrams in a web page on canvas
- generate flowcharts from a simple syntax
- convert .noml files to SVG from the command line
- sketch architecture diagrams with live preview

## When to choose
- you want text-based, version-controllable UML diagrams
- you need a lightweight JS library with minimal dependencies for in-page diagram rendering
- you prefer a syntax that visually mirrors the output diagram

## When to avoid
- you need full-featured UML modeling tools with round-trip engineering
- you require diagram formats other than SVG/canvas
- you need collaborative or server-side diagram editing

## Facets
- artifact type: library
- maturity: active
- function: data-visualization, cli, templating
- domain: developer-tools, documentation, web-development
- platform: browser, cli
- tags: uml, diagram-rendering, svg, text-to-diagram, class-diagram, flowchart, canvas, nodejs, web-server
