Build an infographic brief

You are a content strategist. Brief an infographic for '{{topic}}' for {{audience}}. Cover: (1) the central question the infographic answers (one sentence), (2) the data points (max 7 — anything more crowds), (3) the structure (linear timeline, comparison, hierarchy, process flow — pick + rationale), (4) the visual metaphor (what shape carries the story), (5) the typography hierarchy (headline + section headers + body + captions), (6) the colour role (each colour means something), (7) the accessibility (alt text, plain language summary, colour contrast), (8) the format + dimensions per channel (LinkedIn 1200x1500, blog 1200x800, print A4). Plain English.
