Sample Infographic Engineering Process 4-Step Poster

Educational infographic poster titled "Sample Engineering Infographic" in portrait layout, designed for students / classroom use, with sharp readable text labels in clean sans-serif typography. Create a simple 4-step numbered sequence with large visible step numbers, short captions, and clear connecting arrows flowing from top to bottom. Use isometric 3D visuals, high-contrast yellow & navy palette, crisp white background accents, magazine-grade editorial illustration, vector-clean lines, no photographic textures.

1. heading: "Input"; caption: "Raw information enters the system."; visual: isometric 3D module showing a yellow input tray feeding navy data blocks into a simplified machine housing, with a bold circular number "1" and a right-pointing arrow entering the unit.

2. heading: "Processing"; caption: "The core engine transforms the input."; visual: isometric cutaway of a compact engineering processor with visible gears, circuit paths, and rotating cogs inside a navy machine box, highlighted in yellow, with a bold circular number "2".

3. heading: "Output"; caption: "Useful results are produced and released."; visual: isometric output channel ejecting organized yellow panels, charts, and signal bars from the machine, with a bold circular number "3" and directional arrow pointing outward.

4. heading: "Feedback"; caption: "Results loop back to improve the next cycle."; visual: curved dotted arrow returning from the output area back toward the input side, with a small isometric control dial and check indicator, plus a bold circular number "4".

Show the full flow with thick navy arrows between steps 1 to 2 to 3, then a dotted yellow return arrow from 4 back to 1. Include small legend-style labels near each component, minimal classroom-friendly callouts, consistent spacing, and clear sequence hierarchy. Overall mood: clear, modern, energetic, approachable, technical but simple. Avoid logos, copyrighted characters, identifiable people, and any unnecessary clutter.

All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no watermarks Render labels and headings in clean English typography (sans-serif). No real-brand logos, no copyrighted characters, no people that could be identified, no graphic medical content. If the topic touches a regulated domain (medicine, finance, law), keep the explanation conceptual and add no specific dosages, prices or legal advice.
