Cubes: A number raised to the third power is a cube. Plot the first five cubic numbers, and then
plot the first 5000 cubic numbers.
Colored Cubes: Apply a colormap to your cubes plot
Molecular Motion: Modify rw_visual.py by replacing plt.scatter() with plt.plot(). To simulate the
path of a pollen grain on the surface of a drop of water, pass in the rw.x_values and rw.y_values, and
include a linewidth argument. Use 5000 instead of 50,000 points.
