FAQPage Schema
How do I generate architecture diagrams from a codebase?▼

To generate architecture diagrams from a codebase, you can parse code structure and output diagram syntax. This process visualizes components, dependencies, and interactions across Mermaid, PlantUML, or ASCII formats.

Can I visualize component interactions and data flow using Mermaid or PlantUML?▼

Yes, you can visualize component interactions and data flow using Mermaid or PlantUML. The tool parses code relationships to output diagram syntax specifically for documentation and architecture reviews.

What is the best way to map dependencies across architecture layers for a large codebase?▼

The best way to map dependencies across architecture layers is by automatically parsing the code structure. This produces clear diagrams showing modules and their relationships for large codebase reviews.

Does this approach support ASCII format for codebase visualization?▼

Yes, this codebase visualization approach supports ASCII format alongside Mermaid and PlantUML. You can parse code relationships and output the chosen diagram syntax with included reference guides.

When do I need to use PlantUML or ASCII formats for architecture documentation?▼

You need PlantUML or ASCII formats for architecture documentation when visualizing component interactions and dependencies. These formats help reveal architecture layers and data flow directly from codebase analysis.
