What is the significance of the INCREMENT variable?

The INCREMENT variable is significant because it specifically controls how much the radius of a circle increases with each iteration or frame of the animation. In the context of animations or graphics programs, such a variable is crucial for dynamic transformations, allowing developers to create effects of enlargement or growth over time. By defining the value of INCREMENT, the program can precisely dictate the rate at which the circle expands, contributing to the desired visual outcome.

In this way, the INCREMENT variable plays a fundamental role in the animation logic, directly influencing the appearance and behavior of the shapes being rendered. It doesn’t impact execution speed, the total number of circles, or color limitations, making its function uniquely tied to the manipulation of the circle's physical dimensions in the program.
