In the Circle Wall code, what does the variable 'counter' track?

The variable 'counter' is used to keep track of the number of circles that have been drawn in the Circle Wall code. It increments each time a circle is successfully drawn, allowing the program to know how many circles have been created so far. By using this counter, the code can manage the placement, spacing, or any specific characteristics of the circles based on their count. This makes it essential for creating patterns or ensuring that the circle drawing adheres to certain conditions, such as limiting the total number of drawn circles or determining when to stop the drawing process.

While concepts like the current position of the circle, the color of the circle, or the speed of the drawing process may be relevant in other contexts, the primary role of 'counter' in this scenario is specifically to track the quantity of circles that have been drawn.
