A line chart is a way of plotting data points on a line. Often, it is used to show trend data, or the comparison of two data sets.

Line charts can be configured into stacked area charts by changing the settings on the y axis to enable stacking. Stacked area charts can be used to show how one data trend is made up of a number of smaller pieces.

A bar chart provides a way of showing data values represented as vertical bars. It is sometimes used to show trend data, and the comparison of multiple data sets side by side.

A radar chart is a way of showing multiple data points and the variation between them. They are often useful for comparing the points of two or more different data sets.

Pie charts are probably the most commonly used charts. They are divided into segments, the arc of each segment shows the proportional value of each piece of data.

Doughnut Chart are also registered under two aliases in the Chart core. Other than their different default value, and different alias, they are exactly the same.

Polar area charts are similar to pie charts, but each segment has the same angle - the radius of the segment differs depending on the value.

A bubble chart is used to display three dimensions of data at the same time. The location of the bubble is determined by the first two dimensions and the corresponding horizontal and vertical axes. The third dimension is represented by the size of the individual bubbles.
