Bubble Chart

A bubble chart is a type of scatter plot where data points are displayed as bubbles, with the size of each bubble representing a third data dimension. This visualization lets you show relationships between three numeric variables simultaneously.

• Comparing three numeric variables at once
• Showing the relationship between different measurements
• Identifying patterns and outliers in multidimensional data
• Visualizing proportions and quantities together

• Choose appropriate scales for axes and bubble sizes
• Use color to add an optional fourth dimension of data
• Keep the number of bubbles manageable to avoid overcrowding
• Include clear labels and legends for all dimensions
• Consider using transparency for overlapping bubbles
