❓ Frequently Asked Questions
What is a bar chart and when is it used?
A bar chart uses rectangular bars to compare values across categories. Use it for discrete categories and to show differences in magnitude.
What is a line chart and when is it used?
A line chart plots data points connected by lines to show trends over time or a continuous variable. Use it to reveal changes and patterns.
What is a pie chart and when is it used?
A pie chart shows parts of a whole as proportional slices. Use it to illustrate relative shares when the total is meaningful and there are a few categories.
