Episode notes
When Style Justifies Breaking Rules
- Aesthetics sometimes must bend to attract attention, but not to the point of misleading viewers.
- Kosara warns against dogmatic purity when a more engaging visual prompts correct actions.
Tree Maps Repurposed Successfully
- Tree maps were designed for deep hierarchical file views but found new life as part-to-whole comparisons.
- Practitioners repurposed them because they create large, easily comparable rectangles unlike pie charts.
Use Animation Only To Guide Attention
- Use animation and color sparingly as attention mechanisms rather than constant decoration.
- Avoid excessive bouncing or textures that distract from the data's message.
