Variable Forms Exercise - Jacob's Pyramid (not to be confused with Omkar's Pyramid)

I tracked my sleep for the past two months as my dataset. The resulting processing image is a series of rounded squares, located randomly. The size and color depends on the quality of sleep -> the less sleep, the smaller and redder the square (notice all the very small red squares, i.e. naps), while large, blue squares indicate a good night of sleep.
