Bubble Chart
A Bubble Chart visualizes datasets across three or four dimensions simultaneously. The first two dimensions are plotted along the X-axis and Y-axis, while the remaining dimensions are represented by the bubble size and optionally the bubble color.
Bubble charts are particularly effective for showing relationships and distribution across multiple variables, making them popular in financial and economic analysis, as well as customer and market segmentation studies.
Best Situations to Use
Use a bubble chart when:
You have three or more data series to represent simultaneously.
The size of the data points (bubbles) conveys meaningful information (e.g., market share, profit, customer count).
You need to visualize correlations or outliers across multiple variables.
Comparing data distributions where magnitude differences matter.
Examples:
Plotting financial performance where X = revenue, Y = profit, bubble size = market share.
Customer segmentation where bubble size = total spend and bubble color = loyalty tier.
Comparing product portfolios across categories and contribution levels.
Variations
Bubble charts can be styled and customized into different visual formats:
Plain Base Bubble Chart – Standard representation with circular bubbles.
Gradient Base Bubble Chart – Bubbles filled with gradient effects for improved aesthetics.
Ring Base Bubble Chart – Hollow circular bubbles for a cleaner look and differentiation.

Example Use Cases
Finance: Compare revenue vs. profit, with bubble size = market capitalization.
Marketing: Customer segmentation where bubble size = total purchase value and bubble color = campaign response rate.
Operations: Visualize supplier performance with cost vs. delivery time, bubble size = volume purchased.
Education Analytics: Plot student scores (X = math, Y = science) with bubble size = attendance and bubble color = grade.
Sample Data Setup:
Category Field: Year (or other categorical variable).
Series Fields: At least three numeric fields (X, Y, Size, optional Color).
⚠️ Note: Category fields can be string, numeric, or date types, but series fields must be numeric.
