A Learning Path

A practical chronological learning order is:

Step 1 — Learn the Code Block

flowchart LR
    A --> B

Step 2 — Learn Nodes and Edges

flowchart LR
    A[Start] --> B{Decision}

Step 3 — Learn Flowchart Logic

flowchart TD
    A --> B{Valid?}
    B -->|Yes| C[Continue]
    B -->|No| D[Stop]

Step 4 — Learn Subgraphs

flowchart TB
    subgraph Frontend
        A --> B
    end

    subgraph Backend
        C --> D
    end

    B --> C

Step 5 — Learn Time-Based Interaction

sequenceDiagram
    User->>Server: Request
    Server-->>User: Response

Step 6 — Learn System State

stateDiagram-v2
    [*] --> Idle
    Idle --> Running
    Running --> [*]

Step 7 — Learn Data Models

    USER ||--o{ POST : writes

Step 8 — Learn Object Models
