# Mermaid Architect Guide
Design complex, multi-view system architectures and research infrastructure diagrams using advanced Mermaid features including C4 diagrams, hand-drawn rendering mode, subgraph nesting, and theme customization.
## Overview
While basic Mermaid flowcharts are widely known, Mermaid's advanced capabilities enable sophisticated architectural documentation that rivals dedicated tools like Structurizr or Draw.io. This skill focuses on the architectural use cases that matter most to research teams: depicting multi-layer systems, data pipelines, deployment topologies, and complex experimental workflows.
Mermaid v11+ introduced a hand-drawn rendering mode (via the `handDrawn` look) that produces a sketch-like aesthetic similar to Excalidraw but with the convenience of text-based Markdown embedding. This makes it ideal for research proposals and informal documentation where a polished diagram would feel premature.
Research software systems often involve intricate interactions between data sources, processing pipelines, ML models, and visualization layers. The C4 model support in Mermaid allows teams to document these systems at multiple levels of abstraction -- from high-level context diagrams down to detailed component views -- all in version-controlled Markdown files.
