# Concept note — Mohenjo-daro Grew; Its House-Size Gap Shrank

## Creative approach

The infographic is built as a photographed archaeological survey wall rather than graphics placed over ruins. Every element—headline, labels, seals, and house footprints—is carved, stamped, or raised from the same sun-baked Indus brick as the city itself.

The main DK-G South relief makes narrowing inequality physically visible: highly varied house footprints at left converge toward more similar areas across the sequence, ending at the stamped **0.23** seal. Below it, two separate artifacts prevent the most important scope error. The round **Whole City 0.44** seal stands alone; the **Ur + Ugarit >0.6** comparison has its own relief and does not connect to DK-G South as a single trend.

## Visual system

- Exact 4:3 landscape at 1448 × 1086 pixels.
- Fired buff and grey-rose brick, dust-filled mortar, hard high sunlight, and deep relief shadows.
- One headline, exactly three numerical figures, and exactly three scope labels.
- House footprints—not bars—carry the comparison and direction through time.
- No palace, royal figure, pyramid, ziggurat, modern skyline, political symbol, population claim, or statement that the civilisation as a whole was egalitarian.
