A series is a collection of related data points. The Chart provides an individual plugin for each series type. All the plugins have the pointComponent that renders the series points; the LineSeries, SplineSeries, and AreaSeries plugins also have the seriesComponent that renders the path (line or area) connecting the series points.
The LineSeries plugin visualizes data as a collection of points connected by a broken line.
The SplineSeries plugin connects the points by a line as well, but that line is smooth.
The AreaSeries plugin draws an area filled with a color. This area is limited on top by a broken line.
The ScatterSeries plugin draws a collection of scattered points.
The BarSeries plugin vizualizes data as a collection of bars.
The PieSeries plugin visualizes data as a circle divided into sectors that each represents a portion of the whole.
The pointComponent property allows you to customize the points' appearance. The following example shows how to change the points' shape. d3-shape (a 3rd-party plugin) provides the shapes.
