Render DAG instead of tree in `show` command

Research on libraries below. Validate which of these are well used and maintained. Start simple by trying asciidag if suitable.

For a robust, TypeScript-compatible CLI tool that mimics the git log --graph style while handling multiple roots and layered structures, d3-dag is the most capable engine, though it requires a small amount of "glue" to output ASCII/Unicode for the terminal. [1, 2, 3]
Top Recommendations for TypeScript CLI DAGs

• d3-dag: The "gold standard" for DAG layout in the JS/TS ecosystem.
• Multiple Roots & Layers: Native support for "stratifying" data from various roots and calculating hierarchical layouts.
  • CLI Implementation: Since it's a layout engine rather than a renderer, you can use its calculated coordinates to draw lines and nodes using characters like │, ╯, and *.
• gitgraph-node: Part of the Gitgraph.js suite, specifically designed for Node.js environments.
• Style: Precisely matches the git log aesthetic.
  • Constraint: While robust for "branch and merge" styles, it may require more manual configuration if your "layered types" don't map perfectly to a branch-based metaphor.
• asciidag: A direct Python-to-TypeScript/JavaScript port of the actual Git log graphing algorithm.
• Robustness: Uses the mechanical logic of Git's own source to render ASCII art.
  • Simplicity: Best if you just want to pass in a list of parent-child relationships and get a string back. [1, 4, 5]

Implementation Pattern for "Layered" Types
Since you have a hierarchy of types, you can combine a layout engine with a terminal styling library: [6]

1. Layout: Use d3.dagStratify() to process your nodes, which handles multiple roots automatically.
2. Styling: Map your "hierarchical types" to specific colors or symbols using Chalk or Inquirer to make the layers visually distinct in the CLI.
3. Rendering: Use the coordinates from the layout to print rows of text, inserting the graph characters (like *, |, /) in a left-hand column while your node data stays on the right. [1]

Would you prefer a code snippet showing how to set up d3-dag for a basic CLI layout, or a more lightweight alternative that requires zero configuration?
