gradient
Definition
A gradient is a gradual change in something. For example, the temperature might have a gradient from hot to cold, or the colour of a rainbow might have a gradient from red to violet.
Gradients can be represented by lines or curves. For example, a line graph can show the gradient of temperature over time.
Gradients are used in many different ways. For example, they can be used to map the elevation of a landscape or to show the distribution of something, such as population density.
