## What it is
WaveDrom is an open-source digital timing diagram (waveform) rendering engine that converts a textual WaveJSON description into SVG vector graphics using JavaScript and HTML5. It ships as a browser-embeddable library, an online editor, a rendering server, and a CLI tool for generating SVG files.

## Use cases
- draw digital timing diagrams from text
- render waveforms in documentation as svg
- generate timing diagram svg from json5 file
- embed waveform diagrams in a webpage
- document signal timing for hardware design
- render waveforms in markdown via a server

## When to choose
- you need reproducible, text-based timing diagrams for hardware/IC documentation
- you want to embed waveform diagrams in web pages or markdown files
- you prefer describing diagrams in a compact JSON format rather than drawing them

## When to avoid
- you need general-purpose diagramming beyond digital timing waveforms
- you want a GUI-first diagram editor with drag-and-drop
- you need analog or non-digital signal visualization

## Facets
- artifact type: library
- maturity: active
- function: data-visualization, cli, templating
- domain: developer-tools, documentation, hardware, web-development
- platform: browser, cli
- tags: svg, waveform, timing-diagram, wavejson, digital-hardware, json5, nodejs, web-server
