1. heading: "Early Settlements"; caption: "Small farming communities formed the first organized villages."; visual: bold number 1 in a circle, simple icon of a river beside clustered huts, rectangular crop fields, grain symbols, and a tiny map-pin style marker.

2. heading: "City-States Rise"; caption: "Trade, writing, and leadership systems shaped early urban life."; visual: bold number 2 in a circle, clean diagram of walled city blocks, a small market stall icon, clay tablet with writing lines, and arrows showing exchange routes between buildings.

Make each stage visually distinct but stylistically unified, with short captions directly under each bold heading and sequence arrows clearly guiding the reading order.

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.
