Handwritten Infographic Space Poster in 4 Clear Steps

Educational infographic poster titled "How a Handwritten Infographic Is Built" in portrait layout, designed as an astronomy / space themed educational infographic with sharp, readable text labels in clean sans-serif English typography. Create a simple 4-step sequence with large numbered markers, short captions, and clear connecting arrows flowing from top to bottom. Theme the visuals around planning a space-education handwritten infographic, using isometric 3D objects, technical diagram cues, and editorial clarity.

1. heading: "1. Topic Sketch"; caption: "Choose a space subject and draft the main idea." Visual: isometric yellow notebook page on a navy desk, with rough handwritten-style layout boxes, a small rocket icon, planet doodles, star symbols, and a penciled title area; include a callout arrow pointing to the title block.

2. heading: "2. Structure the Steps"; caption: "Break the idea into 3 to 4 clear components." Visual: isometric card layout showing four stacked content panels, each with a number badge, tiny orbit diagram, moon phase icon, telescope symbol, and short placeholder line bars; add dotted alignment guides and a small flowchart arrow between panels.

3. heading: "3. Add Visual Cues"; caption: "Use diagrams, arrows, and icons to guide the reader." Visual: isometric cutaway-style panel with a labeled orbit path around a planet, directional arrows, a simplified satellite, constellation dots connected by lines, and a small legend box; emphasize arrows and diagram links.

4. heading: "4. Final Clean Poster"; caption: "Refine contrast, spacing, and readable labels." Visual: polished isometric final infographic board pinned upright, showing crisp headings, balanced spacing, yellow-highlighted section headers, navy background panels, neat icon set of rocket, planet, stars, and telescope, plus a clear sequence path from 1 to 4.

Show the connecting flow with bold yellow arrows, subtle dotted guide lines, and visible sequence numbers in circles. Include small technical annotation marks, grid hints, and editorial callouts to make it feel useful for enthusiasts. Visual style: isometric 3D, high-contrast yellow and navy palette, clean geometric forms, precise lighting, modern technical mood, minimal but informative composition, magazine-grade editorial illustration, vector-clean lines, no photographic textures. No brand logos, no copyrighted characters, no identifiable people. 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.
