Architecture Diagram Generator

Quick Start: Create HTML structure with flexible layout (single/double/triple column) → Define CSS styles for layers and grids → Add content with categorized panels → Use semantic colors for different layers.

Critical Rules

Rule 1: Direct HTML Embedding

IMPORTANT: Write architecture diagrams as direct HTML in Markdown. NEVER use code blocks (```html). The HTML should be embedded directly in the document without any fencing.

Rule 2: No Empty Lines in HTML Structure

CRITICAL: Do NOT add any empty lines within the HTML architecture diagram structure. Keep the entire HTML block continuous to prevent parsing errors.

Rule 3: Incremental Creation Approach

RECOMMENDED: Create architecture diagrams in multiple steps:

1. First: Create the overall framework (wrapper, sidebars, main structure) and define all CSS styles
2. Second: Add layer containers with titles
3. Third: Fill in components layer by layer
4. Fourth: Add detailed content and refinements

Rule 4: Flexible Layout Structure

Architecture diagrams can use flexible layouts based on complexity:

• Single Column: Main content only (for simple architectures)
• Two Column: Main content + one sidebar (left or right)
• Three Column: Full layout with both sidebars (for complex systems)
  • Left Sidebar: Supporting systems (monitoring, operations, analytics)
  • Main Content: Core architecture layers (user, application, data, infrastructure)
  • Right Sidebar: Cross-cutting concerns (security, compliance, governance)

Rule 5: Layer-Based Organization

Each layer should have:

• Clear semantic meaning (User, Application, AI/Logic, Data, Infrastructure)
• Consistent color coding
• Grid-based layout for components
• Appropriate nesting for sub-components

Rule 6: Color Semantics

Use consistent semantic meaning for layers — the exact color palette varies by style (see examples). The standard semantic mapping:

• User Layer — user-facing interfaces and clients
• Application Layer — business logic and API services
• AI/Logic Layer — intelligence, rules, processing engines
• Data Layer — databases, caches, storage
• Infrastructure Layer — containers, networking, DevOps
• External Services — third-party APIs, cloud services (typically dashed border)

Style Examples

Choose a visual style that matches your project's tone and audience. Each example contains a complete, copy-ready HTML template.

SVG Connectors Between Components

Use an SVG overlay to draw orthogonal (right-angle) connectors between components. Always use <path> with M/L commands for strictly horizontal and vertical segments. Do NOT use <line>, Bézier curves, or diagonal lines. See layouts/connectors.md for full reference.

<!-- Wrap diagram content in a relative container -->
<div style="position: relative;">
  <!-- ...layers and components here... -->
  <!-- SVG overlay as last child -->
  <svg style="position: absolute; top: 0; left: 0; width: 100%; height: 100%; pointer-events: none; overflow: visible;">
    <defs>
      <marker id="arrowhead" markerWidth="8" markerHeight="6" refX="8" refY="3" orient="auto">
        <path d="M0,0 L8,3 L0,6" fill="none" stroke="#94a3b8" stroke-width="1"/>
      </marker>
    </defs>
    <!-- Orthogonal solid arrow (vertical → horizontal → vertical) -->
    <path d="M 200,72 L 200,90 L 400,90 L 400,108" class="arch-conn" marker-end="url(#arrowhead)"/>
    <!-- Orthogonal dashed line -->
    <path d="M 600,72 L 600,90 L 600,90 L 600,108" class="arch-conn-dashed" marker-end="url(#arrowhead)"/>
    <!-- Label -->
    <text x="420" y="86" class="arch-conn-label">data flow</text>
  </svg>
</div>

Best Practices

HTML Usage Guidelines

1. Direct embedding only — Always embed HTML directly in Markdown, never use ```html code blocks
2. No empty lines in structure — Keep the entire HTML block continuous without any empty lines
3. Incremental development — Build diagrams step by step:
   • Start with basic framework and layout structure (single/two/three column as needed)
   • Add empty layer containers with proper CSS classes
   • Fill in content layer by layer from top to bottom
   • Refine content and add highlights last

Architecture Design

1. Keep layers logically separated — Each layer should represent a clear architectural tier
2. Use consistent naming — Follow naming conventions for components and services
3. Highlight key components — Use .highlight class for critical components
4. Add technical details — Include technology stack info in <small> tags
5. Balance information density — Don't overcrowd components with text
6. Use icons sparingly — Add emojis to titles for visual hierarchy
7. Maintain color semantics — Stick to the established color meanings
8. Consider responsive design — Grids automatically adapt to content

Capability Upgrade

Mode Selection

• Quick: 生成一张清晰的分层架构图。
• Standard: 输出业务、应用、数据、集成、基础设施和安全层的完整架构视图。
• Deep: 结合非功能需求、部署约束、数据流、系统边界和演进路线，形成架构说明包。

Architecture Decision Logic

架构图必须先明确目标：现状说明、目标蓝图、迁移路线、微服务拓扑、数据平台、AI 系统或安全架构。目标不同，层级、组件和连接关系不同。

Quality Gates

• 图中每个组件都有明确职责。
• 数据流、控制流和依赖关系不混淆。
• 关键非功能需求如性能、安全、可用性已反映。
• 没有为了美观加入无业务含义的组件。
• 输出能直接嵌入方案、PPT 或技术文档。
