Chart types
Four formats, one tool
Line chart
Best for trends over time — sales over months, traffic by day, or temperature across hours.
Bar chart
Perfect for side-by-side comparisons — revenue by team, headcount by department, or budget allocation.
Pie chart
Ideal for showing proportions — market share, category distribution, or survey response breakdowns.
Bubble chart
Great for three-dimensional data — x position, y position, and bubble size all encode independent values.
