Choose the right chart type to tell the clearest story with your data.

Last updated

What it is

The strategic selection of data visualization formats based on the type of data, the relationship you want to show, and the action you want the audience to take. Different chart types serve different communication purposes.

Before & after

Before

Using a pie chart to show 12 different categories or a line chart for unrelated categorical data.

After

Bar chart to compare quarterly sales across regions, line chart to show customer acquisition trends over 24 months.

When you’ll use it

Trend analysis: Line charts for performance over time, area charts for cumulative effects, slope charts for before/after comparisons

Category comparison: Bar charts for rankings, grouped bars for multi-category comparison, stacked bars for part-to-whole with categories

Relationship exploration: Scatter plots for correlations, bubble charts for three-variable relationships, heat maps for matrix comparisons

Pro tip

Match the chart to your message: comparison (bars), trend (lines), part-of-whole (pie), correlation (scatter).
