FAQPage Schema
How do I generate Mermaid diagrams from code to visualize software architecture?

You can generate Mermaid diagrams from code by running the diagramming-code skill, which automates code visualization by extracting code graphs and rendering them into structural relationship maps. It requires Trailmark for code analysis to ensure accurate mapping.

What types of code visualization diagrams can I create for a large codebase?

Code visualization supports generating various custom Mermaid diagrams, including call graphs, class hierarchies, module dependency maps, and complexity heatmaps. These diagrams help identify architectural hotspots and understand component relationships within large codebases.

Do I need Trailmark to analyze code and map module dependencies?

Yes, Trailmark is a required dependency for analyzing code and mapping module dependencies. It performs the pre-analysis necessary to extract accurate code graphs, which are then used to automate the generation of Mermaid diagrams.

How do I create a call graph diagram for a specific function in my code?

To create a call graph diagram, run the diagramming-code skill with parameters specifying the target directory, diagram type, focus function, and depth. For example, use `--type call-graph --focus main --depth 2` to visualize specific function relationships.

What is the best way to visualize complex code relationships during software maintenance?

The best way to visualize complex code relationships during software maintenance is to automate Mermaid diagram generation from code graphs. This approach quickly maps call graphs and class hierarchies, helping developers understand structures and identify hotspots efficiently.
