Definition
A graphical representation that shows three-dimensional data in two dimensions using contour lines; each line connects points of equal value. Often used in geography (topographic maps) or engineering to visualize gradients and surfaces.

Example Alt Text
"Two contour plots labeled a and b show range versus azimuth distributions. Concentric contour lines form a strong central peak near range 18.7 meters and azimuth 4.8 meters. Smaller symmetric side lobes appear above, below, and beside the center. Contour intensity decreases outward from the central region, creating similar spatial patterns in both panels."
