Crate graphs_tui 

graphs-tui - Terminal renderer for Mermaid and D2 diagrams

Mermaid Flowchart Example

use graphs_tui::{render_mermaid_to_tui, RenderOptions};

let input = "flowchart LR\nA[Start] --> B[End]";
let output = render_mermaid_to_tui(input, RenderOptions::default()).unwrap();
println!("{}", output);

State Diagram Example

use graphs_tui::{render_state_diagram, RenderOptions};

let input = "stateDiagram-v2\n    [*] --> Idle\n    Idle --> Running";
let output = render_state_diagram(input, RenderOptions::default()).unwrap();
println!("{}", output);

Pie Chart Example

use graphs_tui::{render_pie_chart, RenderOptions};

let input = "pie\n    \"Chrome\" : 65\n    \"Firefox\" : 35";
let output = render_pie_chart(input, RenderOptions::default()).unwrap();
println!("{}", output);

D2 Example

use graphs_tui::{render_d2_to_tui, RenderOptions};

let input = "A -> B: connection";
let output = render_d2_to_tui(input, RenderOptions::default()).unwrap();
println!("{}", output);

Sequence Diagram Example

use graphs_tui::{render_sequence_diagram, RenderOptions};

let input = "sequenceDiagram\n    Alice->>Bob: Hello\n    Bob-->>Alice: Hi!";
let output = render_sequence_diagram(input, RenderOptions::default()).unwrap();
println!("{}", output);

Auto-detect Format

use graphs_tui::{render_diagram, RenderOptions};

let mermaid_input = "flowchart LR\nA --> B";
let d2_input = "A -> B";

// Automatically detects format
let _ = render_diagram(mermaid_input, RenderOptions::default());
let _ = render_diagram(d2_input, RenderOptions::default());
