There are three primary types of charts: line charts, bar charts, and pie charts.
Line charts are used to visualize changes over time. For example, you could use a line chart to visualize the closing price of a stock over time.
Bar charts are used to visualize comparisons. For example, you could use a bar chart to compare the sales of two products.
Pie charts are used to visualize proportions. For example, you could use a pie chart to visualize the percentage of people who prefer each type of ice cream.
