About:
D2 is a modern diagram scripting language designed to turn text into diagrams dynamically. It allows developers to define complex layouts and relationships using a simple, readable syntax. The tool focuses on automating diagram generation for documentation, infrastructure, and code architecture.

Key Features:

Text-to-diagram conversion with a simple scripting language
Live reloading for instant visual feedback during editing
Flexible layout engine that automatically arranges elements
Support for exporting to SVG, PNG, and other formats

Use Cases:

Generating infrastructure and architecture diagrams from code
Creating documentation diagrams that are version-controlled
Visualizing complex data structures and relationships

Alternatives:

Graphviz – Graphviz uses DOT language and is older; D2 offers a more modern syntax and better automatic layout features.
Mermaid – Mermaid is JS-based and widely integrated; D2 provides a more powerful layout engine and standalone binary.
