The 10 Principles

1. Most Important Metric Top-Left

Western readers scan top-left first. Put your key metric there.

2. Maximum 5-7 Visuals

More = cognitive overload. If you need more, create multiple pages.

3. Tell a Story

Don’t just show data. Guide users through insights.

4. Use Consistent Colors

Green = positive/up
Red = negative/down
Blue = neutral
Gray = reference

5. Direct Labels > Legends

Label your data points directly instead of forcing users to look at legends.

6. Remove Chartjunk

Delete gridlines, borders, and unnecessary decorations.

7. Make It Actionable

Every dashboard should answer “So what should I do?”

8. Design for Your Audience

CEO: High-level KPIs only
Manager: Trends and comparisons
Analyst: Drill-down capabilities

9. Test on Mobile

60% of dashboards are viewed on tablets/phones.

10. Update Data Automatically

Manual updates = dashboard death.
