Let's summarize the concepts we discussed in this chapter.

We built a screen saver and in the process saw how to implement animations on the Tkinter canvas. Next, we saw how to create Cartesian and polar plots on the canvas. We also saw how to embed matplotlib plots on a Tkinter window. 

We then implemented a basic gravity simulation that showed how we could take a physical model and implement it using a Tkinter canvas. We got a glimpse into the implementation of Voronoi diagrams, which are being used to model and solve so many practical real-world problems.  

We also build some nice visualizations such as the Mandelbrot set and Phyllotaxies.

Finally, we learned how to use a Tkinter canvas to draw and animate 3D graphics using transformation matrices.
