Which function allows a new ball to be drawn at the ball's current position in the Trail program?

The function that allows a new ball to be drawn at the ball's current position in the Trail program is drawCircle. This function is responsible for rendering the visual representation of the ball on the screen. It takes into account the current coordinates of the ball and creates a circle at those coordinates, thereby allowing the animation to show the ball's movement effectively.

In animation and game programming, it's essential to continuously update the visual state of objects on the screen. The drawCircle function achieves this by utilizing the ball's current position to ensure that the display reflects the latest state of the ball as it moves. Thus, when you call drawCircle within the game's update loop or relevant function, it redraws the ball at its new location, providing a fluid and dynamic visual experience.
