Explanation

The logo consists of five rings interlaced with each other in five different colors. The blue, black, and red rings are interlaced from left to right at the top, and the yellow and green rings are at the bottom. To create rings using code, we drew five different colored rings and adjust them according to the dimensions of the logo.

Line 3: The radius variable contains the radius of the ring. It is set as 0.5.
Line 4: The thickness variable contains the line thickness or line width of the ring. It is set as 6.0.
Line 5: subplots() function is used to create subplots. The line figure, axes = plt.subplots() returns figure and axes objects.
Line 6: Circle() function creates a circle. It can contain a different number of parameters according to usage. Here, it contains five parameters and returns the circle object. Let’s understand all parameters one by one.
- First parameter ( -1.0 , 0.4 ) is coordinate axes of the circle. The first value corresponds to x-axis and the second one corresponds to y-axis.
- Second parameter is the radius of the circle defined in radius variable.
- Third parameter fill=False leaves the circle unfilled in the shape of a ring. Changing the value to True makes a color-filled circle.
- Fourth parameter is lw which defines the line width (thickness) of the circle boundary. It is set with the thickness variable.
- Fifth parameter sets the value of the color of the circle.
- The same Circle() function creates circles of different colors in lines 7-10.
Line 12: xlim() function sets the limits on the x-axis of current axes. plt.xlim(-2.5, 2.5) means that x-axis is stretched from -2.5 to 2.5.
Line 13: ylim() function sets the limits on the y-axis of current axes. plt.ylim(-1.5, 1.5) means that y-axis is stretched from -1.5 to 1.5.
Line 15: axes.set_aspect(1) sets the aspect ratio of axis scaling. We have set 1 aspect ratio.
Lines 16–20: In these five lines, we are adding five color circle objects created on lines 6-10 into Artist by using add_artist() function and passing the object into it. Artist is a base class that’s rendered into the canvas.
Line 22: plt.title('Olympics Logo') is setting the title.
Line 23: Saving the figure by using savefig() function of figure.
