What you will do is remove those circle calls from the source code, and instead add a loop that reads from a file to get the data to make the calls to the circle function.

# this code draws a bear made of circles

# by repeatedly calling the circle$()$ function.

#

# it could be modified to draw anything

# you want $...$ made of circles.

# move the pen without leaving a line

def relocate $($turt$,$ x $,$ y$)$ :

turt.penup$()$

turt.setx $($x$)$

turt.sety $($y$)$

turt.setheading$(90)$

turt.pendown$()$

# draw a circle at the specified position

def circle $($ turt, x $,$y $,$ radius $,$ color$)$:

SHIFT$\_$X $=40$

SHIFT$\_$Y $=30$

SCALE $=5$

x $=$ x $-$ SHIFT$\_$X

y $=$ y $-$ SHIFT$\_$Y

x $=$ x $*$ SCALE

y $=$ y $*$ SCALE

radius $=$ radius $*$ SCALE
