Spline Chart

Spline Chart is one of the most widespread data visualization types. It looks very similar to the Line Chart type of data visualization. The core difference between them is that data points in a Spline Chart are connected with smooth curves instead of straight lines.

Spline Charts usually display the change of a variable over time (in Cartesian charts) or simply along the X-axis (which is the case for Scatter charts).

The Spline Chart type is the basis for other graphs such as Spline Area Chart, Stacked SplineArea Chart, and more.
