Summary
We have learned three kinds of charts:
a bar chart a line chart a pie chart
Different charts are suitable for displaying various types of data with its unique strengths.
Bar Chart: It is easy to read and understand, making it great for showing differences between groups.
Pie Chart: It is best for showing proportions of a whole. It provides a quick visual representation of how each category contributes to the total.
Line Chart: It is ideal for displaying data trends over time. It is excellent for showing how data points change and can easily illustrate increases and decreases in values.
