Urban System Cross Section Infographic

Generate a [Ultra-wide Urban System Science Popularization Section Long Roll], a single complete image, no puzzles, no multi-grid layouts, no columns, horizontal layout 3:1.

Topic: [Urban Underground Systems / Airport Operation Systems / Hospital Function Systems / Port Logistics Systems / Custom Systems]
Title: [Fill in the Science Popularization Title]
Core Content: [Fill in the space structure, functional zoning, and operation process]
Information Module: [Keep it at 6–8]
Style: [Advanced Science Popularization Display Board / System Section Infographic / Illustrated Knowledge Visualization]
Color scheme: [fill in main color]

The focus of the visuals is to clearly explain the surface, internal structure, functional zoning, and operational processes of complex systems all at once.
Maps are the main focus, writing is the supplement. Use only short tags, module names, functional terms, and a very brief description in the text—avoid long paragraphs or crowded sections.

A small number of numbering, arrows, flow lines, fine line annotations, and legend bars can be added so viewers can understand how the system works.

The overall image resembles the exhibition hall's popular science scroll, urban system infographics, and advanced cross-sectional diagrams in PPT proposals.

Avoid overly filled text, cluttered information, puzzle-like textures, multi-grid grids, ordinary landscape images, and low resolution.
