Raw numbers don’t tell a clear story. Visualization turns data into something your brain can quickly understand.
🎯 Why Visualization Matters:
- Reveals hidden patterns
- Helps detect errors/anomalies
- Makes communication easier
🔍 Example:
A table of sales numbers vs a line chart of sales → the chart instantly shows growth or decline.
❓ Check Your Understanding:
- Why is visualization better than tables for large datasets?
- Can visualization ever mislead? When?
- What happens if you skip visualization in analysis?

| Month | Sales |
|---|---|
| Jan | 200 |
| Feb | 250 |
| Mar | 300 |
