## How it works

An interactive text-grid editor for creating ASCII art diagrams.

The tool manages a customizable grid of monospace cells. A JavaScript drawing engine manipulates a 2D character array upon mouse actions (e.g. line connections or box creation using '+', '-' and '|' characters). The finished diagram can be exported directly as raw text.

Manages a two-dimensional character grid in memory. Mouse actions map to coordinates, writing border and arrow characters into the matrix to render monospace text in real time.
