## What it is
Fletcher is a Typst package for drawing diagrams with nodes and arrows, built on top of CeTZ. It supports commutative diagrams, flowcharts, state machines, and other arrow-based diagrams directly in Typst documents.

## Use cases
- draw commutative diagrams in math papers
- create flowcharts in typst documents
- draw state machine diagrams
- tikzcd alternative for typst
- render feynman diagrams
- add node-and-arrow diagrams to typeset documents

## When to choose
- you write documents in Typst and need arrow-based diagrams
- you want a TikZ-cd-like experience for commutative diagrams without LaTeX
- you need flowcharts or state machines rendered declaratively in markup

## When to avoid
- you are not using Typst as your typesetting system
- you need general-purpose vector graphics beyond node-and-arrow diagrams
- you need diagrams rendered outside of document typesetting

## Facets
- artifact type: library
- maturity: active
- function: data-visualization, graphics
- domain: data-visualization, documentation, developer-tools
- platform: -
- tags: typst, cetz, diagrams, commutative-diagrams, flowchart, state-machine, tikzcd, arrows
