A line polar chart plots data as connected line segments on a radial coordinate system, where the circular x-axis represents angles and the radial y-axis represents values. It is well suited for visualizing periodic functions and cyclical data patterns.
This sample graphs the classic mathematical functions sin(x) and cos(x) as two line series on a polar plot. The x-axis spans 0 to 360 degrees at 30-degree intervals, and the y-axis range is set from -1 to 1.5 with 0.5 step to pad extreme values. Data is loaded from an external CSV file, and an interactive legend lets you toggle each series on and off.
