A polar plot is a graphical representation of data on a circular grid. Unlike Cartesian plots that use two perpendicular axes (x and y), polar plots use two parameters: an angle and a radius. The angle is measured from a reference direction, typically the positive x-axis, and the radius represents the distance from a central point, known as the origin or pole.

Data points are plotted by locating them at the intersection of a specific angle and a corresponding radius. This makes polar plots particularly useful for visualizing data that has a directional or cyclical component, such as navigational data, sensor readings with a fixed point of reference, or patterns that repeat over time. Common applications include radar displays, sonar readings, wind patterns, and the representation of complex numbers.

The circular nature of the polar plot allows for an intuitive understanding of how values change as direction or rotation occurs. For example, in a radar display, the angle might represent the direction of a target, and the radius its distance. In other contexts, the angle could represent time within a day or a season, and the radius the measured value at that time. The interpretation of a polar plot depends heavily on the meaning assigned to the angular and radial axes within a specific domain.
