Sample Infographic Civilization Timeline Poster

Educational infographic poster titled "Sample Civilization Timeline" in portrait layout, designed for students/classroom, with sharp readable English sans-serif text labels and clean hierarchical typography. Create a 6-step numbered educational sequence about how a civilization develops and changes over time, using clear connecting arrows from top to bottom with small dotted timeline links and large sequence numbers 1-6. Each stage must include a bold heading, a one-line caption, and a precise visual diagram element.

1. heading: "Settlement Begins"; caption: "People gather near water, fertile land, and safe routes."; visual: small map-style scene with a river bend, simple huts, farm plots, and a location pin icon, plus a faint terrain diagram.
2. heading: "Farming Grows"; caption: "Reliable crops and storage support larger communities."; visual: cutaway of grain fields, irrigation channels, storage jars, and a granary cross-section, with small crop icons.
3. heading: "Cities Form"; caption: "Homes, streets, and public spaces create organized urban life."; visual: isometric walled city diagram with roads, clustered buildings, a market square, and labeled civic structures.
4. heading: "Trade Expands"; caption: "Goods, ideas, and materials move across land and sea routes."; visual: trade network map with carts, a sailing boat, amphora-style containers, arrows between regions, and small cargo icons.
5. heading: "Government and Writing"; caption: "Rules, records, and administration help manage complex society."; visual: stone tablet and scroll, stylus icon, simplified archive shelves, and a governance diagram with seal stamp and checklist symbols.
6. heading: "Legacy Remains"; caption: "Artifacts, monuments, and texts help later generations understand the past."; visual: museum-style display of pottery shards, a monument silhouette, stacked manuscripts, and an archaeological layer cutaway with discovery markers.

Use connecting flow with bold blue arrows, dotted timeline lines, and circular number badges linking each stage in order. Add small supporting visual callouts, a simple legend strip for symbols, and subtle timeline markers, but keep the layout uncluttered and readable. Visual style: magazine-grade editorial illustration, professional blue palette with navy, cobalt, slate, and pale ice-blue accents, calm academic mood, polished classroom-friendly composition, vector-clean icons and diagrams, balanced white space, magazine-grade editorial illustration, vector-clean lines, no photographic textures. No logos, no copyrighted characters, no identifiable people, no graphic content.

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.
