Effective data visualization transforms raw numbers into actionable insights.

Bar Charts excel at comparing categories—use them for differences between groups or frequency distributions.

Line Charts show trends over time, ideal for time series data emphasizing patterns of change.

Pie Charts show part-to-whole relationships with few categories (five or fewer).

Scatter Plots reveal relationships between two variables, essential for correlation and regression analysis.

Design Principles apply across all types: minimize chartjunk, use color purposefully, and label clearly.
