Mechanical Bubble Chart

Application Scenario

The mechanical bubble chart presents bubbles in the mechanical diagram format. You can determine whether to display the category name, series name, and value.

The mechanical bubble chart is suitable for showing the relationships among values across multiple data series. Similar to the X and Y axes, the chart helps determine if a correlation between two variables exists or identify the data distribution or aggregation.

The following figure shows the display effect.

Chart Feature

Advantage: The mechanical bubble chart is suitable for handling problems involving value distribution and data point clustering.

Note: Each bubble is spaced evenly at 10px, with larger bubbles positioned as centrally as possible within the chart.
