Area charts display changes in magnitude over time using colored areas below lines. They can be 2D or 3D, stacked to show contribution, or 100% stacked to show percentage contribution over time. Scatter charts show relationships between numeric variables and are used for scientific data. Bubble charts are like scatter charts but show three variables where the third determines bubble size. Stock charts illustrate price fluctuations over time using high, low, close values or including open and volume values.
