Let’s now create a moving coil that slowly unwinds, with the help of animation class of matplotlib. The code is quite similar to the sine wave plot with minor adjustments. The primary difference of plt.scatter from plt.plot is that it can be used to create scatter plots where the properties of each individual point (size, face color, edge color, etc.) can be individually controlled or mapped to data. Let's show this by creating a random scatter plot with points of many colors and sizes. Matplotlib is a plotting library for 2D graphics.
