Bézier (pronounced bAy z A (my attempt at a phonetic spelling)) curve is a mathematically defined curve that can be used to draw "smooth" lines through or near points or lines. (I once offered it (and it was used) as a solution to draw a smooth blast furnace temperature profile on a round graph intended to "geographically" represent the furnace.)

Many (some?) CAD or similar programs (Visio) have means to draw Bézier curves of various sorts.

Just glancing at the sketches in the first two resources will give you a reasonable understanding of what a Bézier curve can be used for:

The following describes the mathematics for the so called Bézier curve. It is attributed and named after a French engineer, Pierre Bézier, who used them for the body design of the Renault car in the 1970's. They have since obtained dominance in the typesetting industry and in particular with the Adobe Postscript and font products.
