Ruby/GraphViz

Provides an object-oriented interface and DSL that aligns with Ruby conventions, allowing graph creation using familiar Ruby blocks and methods for intuitive code.

Includes graph theory modules with methods like Dijkstra's algorithm and critical path calculations, enabling both visualization and computational analysis directly in Ruby.

Comes with command-line tools such as ruby2gv for script dependency graphs and git2gv for commit history, automating common visualization tasks without extra coding.

Supports parsing and converting GraphViz DOT files and GraphML formats, facilitating integration with existing graph data and workflows.
