The document discusses bubble charts, which display three dimensions of data using circles of varying sizes. Bubble charts can show relationships in social, economic, medical, and scientific data sets with dozens to hundreds of values that differ greatly in magnitude. They represent numbers using the area of circles, making them useful for positive values that can differ by ratios of 100,000 while displaying hundreds of values at once. An example bubble chart is presented showing product numbers on the x-axis, sales amounts on the y-axis, and market share percentages as bubble sizes.
