cartograph

Codebase architecture mapping is the process of extracting surfaces, features, entities, and relationships to visualize code structure. Cartograph automates this mapping to generate an interactive UI and code-health metrics for auditing large codebases.

You can visualize code architecture by running `cartograph analyze` to map entities, relationships, and flows into an interactive UI. This visualizes the tech stack and structural compartments to help audit dependencies and identify code health issues.

To verify product-level invariants in a codebase, use Cartograph to define and check architectural constraints against mapped entities and relationships. This invariant verification identifies structural rule violations and ensures codebase compliance.

Yes, you need package.json dependencies for codebase mapping and analysis because Cartograph requires them for parsing and processing code. Ensure your Node.js project has a valid package.json before running `cartograph analyze`.

The best way to audit code health and structural dependencies is by mapping the codebase to extract metrics and relationship flows. Cartograph provides a structured vocabulary and interactive UI to identify potential issues during codebase audits.

You should use codebase mapping for architecture visualization when you need to understand complex structural relationships, extract tech stack metrics, or verify invariants. It is particularly useful for codebase audits and identifying code health issues in unfamiliar projects.
