Mermaid diagrams visualize ROS 2 node graphs, data flows, and state machines by converting text descriptions into flowcharts, graphs, and sequence diagrams. Specify nodes, topics, and message types to create accessible, beginner-friendly diagrams with 5–10 nodes and automatic alt-text for documentation.

Yes. Mermaid diagrams include alt-text generated after each diagram block, meeting accessibility standards for textbooks and educational materials. This ensures screen readers and assistive technologies can interpret perception pipelines, VSLAM mappings, and navigation flows.

Mermaid supports Flowchart, Graph, Sequence Diagram, and State Diagram types. These cover ROS 2 node communication, data-flow pipelines, VLA and Nav2 sequences, sim-to-real calibration, and behavior state transitions with consistent styling and topic-name annotations.

Define nodes for publishers and subscribers, connect them with labeled edges showing topics and message types, then generate a Mermaid graph or flowchart. This maps perception pipelines, motion planners, and sensor chains in a single diagram.

Beginner-friendly diagrams maintain 5–10 nodes to avoid cognitive overload in educational contexts. For larger ROS 2 systems, break architectures into separate diagrams by subsystem—perception, planning, control—then link them conceptually.
