• Legend: Bottom-left corner with visual explanations of line types and symbols

Fonts

• Chinese: Microsoft YaHei (msyh.ttc) or SimHei (simhei.ttf)
• English/Numbers: Arial or Segoe UI
• Title: 22px bold, dark text with underline accent
• Subtitle: 13px, gray-blue
• Card Header: 13px bold, white on color block
• Body Items: 11px, regular, dark text with bullet points
• Layer Name: 12px bold, accent color
• Flow Labels: 10px, blue text

Available Icon Types

Export Formats

PNG (Raster Image)

• Best for: Embedding in documents, presentations, websites
• Resolution: 150 DPI, configurable canvas size
• Features: Full visual effects (shadows, gradients, anti-aliasing)

SVG (Vector Graphics)

• Best for: Scalable output, print, further editing in Illustrator/Figma
• Features: Clean vector paths, editable in design tools
• Limitations: Simplified effects compared to PNG

HTML (Interactive)

• Best for: Web display, interactive exploration, sharing via browser
• Features:
• Hover tooltips showing module names
• Clickable module cards
• Responsive container layout
• CSS animations on hover
• Output: Single self-contained HTML file

PPTX (PowerPoint)

• Best for: Business presentations, editable slides
• Requirements: Node.js + PptxGenJS (npm install pptxgenjs)
• Features: Native PowerPoint shapes, editable text, theme colors
• Fallback: If Node.js unavailable, generates JS template for manual execution

Usage

Python API

from generate_arch_v3 import generate_all, generate_png, generate_svg, generate_html, generate_pptx

# Generate all formats at once
results = generate_all(config, "output_path", formats=['png', 'svg', 'html', 'pptx'])

# Or generate individual formats
generate_png(config, "output.png")
generate_svg(config, "output.svg")
generate_html(config, "output.html")
generate_pptx(config, "output.pptx")  # Requires Node.js + PptxGenJS

As Skill Invocation

When user requests an architecture diagram, follow these steps:

1. Understand Requirements: Clarify the system/business process to display
2. Design Structure: Plan layers (typically 4-6), modules per layer, sidebar, and connections
3. Choose Icons: Select appropriate icon types for each module
4. Define Connections: Map data flow between layers with descriptive labels
5. Add Legend: Include visual legend for line types and symbols
6. Generate Image: Use Python script following the visual specification
7. Deliver Result: Return generated file paths for all requested formats

Key Design Rules

1. Layer count: 4-6 layers is optimal; each layer should have 3-6 modules
2. Module items: 2-5 items per module; keep descriptions concise (2-6 Chinese characters)
3. Connections: Connect modules across adjacent layers; add descriptive flow labels
4. Sidebar: Use for cross-cutting concerns (security, monitoring, DevOps)
5. Canvas size: 1600x1200 for simple diagrams; 1800x1300 for complex ones
6. Always include: Title, subtitle, layer badges, flow labels, and legend

Chinese Font Support

The script auto-detects available Chinese fonts in this priority order:

Windows: Microsoft YaHei > SimHei > SimSun > KaiTi > FangSong macOS: PingFang SC > STHeiti > Hiragino Sans GB > Arial Unicode Linux: WenQuanYi Micro Hei > Droid Sans Fallback > Noto Sans CJK > DejaVu Sans

If no Chinese font is found, falls back to system default. To verify font detection:

from generate_arch_v3 import get_font_info
print(get_font_info())  # Shows detected font family and path

Dependencies

• Python: Pillow (pip install Pillow)
• PPTX export: Node.js + PptxGenJS (npm install pptxgenjs)
• Fonts: System Chinese fonts (auto-detected)

Example Scenarios

• E-commerce system architecture
• Microservices architecture
• Data platform architecture
• AI platform architecture
• Business process flowchart
• Network topology diagram
• Cloud-native architecture
• Education technology system
• Healthcare information system
• Financial technology platform

Notes

1. Ensure Pillow is installed: pip install Pillow
2. Chinese text requires system font support (auto-detected)
3. Increase canvas size when there are many modules
4. Keep hierarchy clear, avoid too many crossing lines
5. Compact layout but not crowded, ensure readability
6. For PPTX export, install Node.js and run npm install pptxgenjs first
7. HTML output is self-contained and can be opened directly in browser
8. SVG output can be imported into Figma, Illustrator, or other design tools
