Angular Charts - Area Sparklines

In this demo, a set of area-like sparklines is placed into a table. Although these sparklines look similar, they have different series types. The first table column contains sparklines of the area series type. In the second table column, spline area sparklines are placed. The third table column displays sparklines of the step area series type.
