AI overview
A contour line is a curve drawn on a map or chart that connects all points having the same value, such as elevation or temperature. Contour lines help visualize how a quantity changes across a geographic area, making it easier to spot patterns and understand the landscape or data at a glance.

The bottom part of the diagram shows some contour lines with a straight line running through the location of the maximum value. The curve at the top represents the values along that straight line. A three-dimensional surface, whose contour graph is below. A two-dimensional contour graph of the three-dimensional surface in the above picture.
A contour line (also isoline, isopleth, isoquant or isarithm) of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value to the state. It is a plane section of the three-dimensional graph of the function
