A sample floor map diagram created to demonstrate systematic, icon-based venue illustration for puzzle and activity book publishing. The map depicts a multi-floor luxury train with labeled rooms, color-coded path lines (guest route, service route, express route), and custom icons throughout. Designed in Adobe Illustrator with a clean, consistent visual system — print-ready CMYK, scalable vectors, and a reusable icon kit. This style is well-suited for puzzle books, educational materials, infographic publishing, and hospitality/transport branding.
