Creating Bubble Plots<br />

Using the Bubble Plot Platform<br />

A bubble plot is a scatter plot that represents its points as circles, or bubbles. Bubble plots can be dynamic<br />

(animated over time) or static (fixed bubbles that do not move). Use bubble plots to:<br />

• dynamically animate bubbles using a time variable, to see patterns <strong>and</strong> movement across time<br />

• use size <strong>and</strong> color to clearly distinguish between different variables<br />

• aggregate data (rows) into a single bubble, simplifying the bubble plot<br />

Because you can see up to five dimensions at once (x position, y position, size, color, <strong>and</strong> time), bubble plots<br />

can produce dramatic visualizations <strong>and</strong> readily show patterns <strong>and</strong> trends.<br />

Note: Dynamic bubble plots were pioneered by Hans Rosling, Professor of International Health,<br />

Karolinska Institutet, <strong>and</strong> the people involved in the Gapminder.org project.<br />
