Visual Idea Vault

Rules for every visual

• Use the canvas for the concept, not for paragraphs.
• Keep the main image to one idea only.
• Move long explanation into the caption or companion note.
• Prefer labels, arrows, callouts, and shape language over sentences.
• If the image starts to look crowded, delete text before shrinking the art.

Text budget

Put inside the image

• title
• one-line takeaway
• 3 to 5 labels
• arrows or numbered steps
• a single trap callout if needed

Keep outside the image

• long examples
• worked derivations
• solution prose
• comparison tables
• caveats and exceptions

Layout heuristics

• One hero object in the center.
• One supporting strip or side rail.
• One accent color per concept.
• Avoid repeated cards or duplicate captions inside the image.
• Use whitespace to show hierarchy.
