Bubble Chart
A Bubble Chart is an excellent tool for visualizing data points with an added dimension of varying bubble sizes. This type of chart is useful for displaying relationships among three variables, making it ideal for showing clusters, trends, and outliers.

How To Read the Visualization
In a Bubble Chart, each bubble represents a data point. The x-axis and y-axis display the two primary variables of interest, while the size of the bubble indicates the third variable’s value. Larger bubbles signify higher values, and smaller bubbles indicate lower values. This visualization allows for quick identification of patterns, correlations, and significant deviations.
Data Structure
Measures: 3 (x-axis, y-axis, bubble size)
Dimensions: 1 (usually categories)
Best Practices / Limitations
Data Points: Best used with moderate data points to avoid clutter and maintain clarity.
Clarity: Ensure there is enough space between bubbles to make individual data points distinguishable.
Color: Use distinct colors to differentiate categories or groups effectively.
