Example 3-12: Set Stroke Weight. draw() function

The next last(or second) line is missing in draw() function:

to return stroke weight to 1.

Else a first ellipse will also have weight 20.

Note from the Author or Editor:
At the moment, but code is fine as it is. The drawing properties are refreshed each time through the draw(). However, I agree that the code is better with the explicit strokeWeight(1). So, to fix, the code should start:

void draw() {
strokeWeight(1); // Stroke weight to 1 pixel
ellipse(75, 60, 90, 90);
