## Project history and usage

Diagram is a Go command-line application for turning ASCII-art sketches into hand-drawn PNG diagrams. Its niche is the overlap between terminal diagramming, rough sketch aesthetics, and quick documentation assets.

### Project history

The public GitHub repository was created in 2017, matching the README copyright year. The README describes Diagram as a full CLI application with an editor, preview window, zooming and panning, file management, and direct command-line conversion from input text to output PNG.

### Adoption history

Diagram is packaged for Homebrew and advertised from its own README with a `brew install diagram` path, which puts it in the small family of diagramming tools installable as normal Unix command-line utilities rather than desktop drawing applications.

### How it is used

Package users typically feed an ASCII diagram to `diagram -in sample.txt -out sample.png`, optionally disabling preview or selecting a handwriting font. That makes it useful for quick README illustrations, sketches, and local documentation workflows.

### Why package nerds care

For package collectors, Diagram is interesting because it packages a visual, GUI-adjacent workflow as a single CLI: text in, generated image out, with a terminal UI available when interactive editing is wanted.

### Timeline

### Related projects

- The README says its ASCII-to-PNG conversion was ported from `shaky.dart`, and lists Go UI/graphics dependencies including gocui, gg, and gioui.
