## What it is
Diagon is an interactive interpreter that transforms markdown-style expressions into ASCII art diagrams, supporting math expressions, sequences, trees, tables, and UML-style diagrams. It is written in C++ and available as a web application (via WebAssembly), a command line tool, and a JavaScript library.

## Use cases
- render math expressions as ascii art in the terminal
- generate ascii sequence diagrams for documentation
- draw ascii trees and tables from plain text input
- convert markdown-style notation into unicode diagrams
- embed ascii diagram generation in a web app
- create ascii diagrams inside vim or vscode

## When to choose
- you need plain-text diagrams for READMEs, comments, or terminals
- you want to typeset math expressions without images or LaTeX
- you prefer a lightweight offline CLI over heavy diagramming tools

## When to avoid
- you need rich graphical diagrams with colors and export to PNG/SVG
- you need collaborative or drag-and-drop diagram editing

## Facets
- artifact type: cli-tool
- maturity: active
- function: parser, interpreter, cli, templating, graphics
- domain: developer-tools, documentation, web-development
- platform: cpp, cli, wasm, cross-platform, windows
- tags: ascii-art, diagram-generator, webassembly, math-notation, uml-diagrams, markdown, unicode, antlr, ide-plugins, command-line, web, linux, macos
