• Discretion Highlighting: Mark areas requiring human judgment

Output Formats

Usage

use legalis_viz::{DecisionTree, DependencyGraph, VizExporter};
use legalis_core::Statute;

// Create decision tree from statute
let statute = /* ... */;
let tree = DecisionTree::from_statute(&statute)?;

// Export to different formats
let mermaid = tree.to_mermaid();
let ascii = tree.to_ascii();

// Create dependency graph
let statutes = vec![/* ... */];
let graph = DependencyGraph::from_statutes(&statutes);
let dot = graph.to_graphviz();

Mermaid Output Example

flowchart TD
    A[adult-rights] --> B{Age >= 18?}
    B -->|Yes| C[Grant: Full legal capacity]
    B -->|No| D[Not applicable]

└── Discretion: Consider special circumstances
