This is a pathfinder codebase written specifically to render plain text visualizations of flows in Gingester.

Example code:

new GraphTxt(List.of(
    SimpleNode.of("AAAAA", "BBBB", "C", "F"),
    SimpleNode.of("BBBB", "F"),
    SimpleNode.of("C"),
    SimpleNode.of("D", "BBBB", "E", "ZZZ", "H"),
    SimpleNode.of("E"),
    SimpleNode.of("F"),
    SimpleNode.of("ZZZ"),
    SimpleNode.of("H", "IIII"),
    SimpleNode.of("IIII")
)).getText()

Will produce:

    ┌───────┐       ┌───┐
    │ AAAAA │       │ D │
    └───┬───┘       └─┬─┘
┌───┬───┴───┐         │
│   │       ├──────┬──┴───┬──────┐
│ ┌─┴─┐ ┌───┴──┐ ┌─┴─┐ ┌──┴──┐ ┌─┴─┐
│ │ C │ │ BBBB │ │ E │ │ ZZZ │ │ H │
│ └───┘ └───┬──┘ └───┘ └─────┘ └─┬─┘
│           │                   ┌┘
└───────────┤                   │
          ┌─┴─┐             ┌───┴──┐
          │ F │             │ IIII │
          └───┘             └──────┘

The layout algorithm keeps the nodes within the horizontal space used by the widest row.
