That second graph is so cool! I decided to make my own real quick:

    import numpy, matplotlib.pyplot    
    matrix = numpy.zeros(10000)
    for i in range(1, 10000):
        counter = 0
        pos = i
        while pos != 1:
            if pos % 2 == 0:
                pos = pos / 2
                counter = 1
            else:
                pos = pos*3  1
                counter += 1
        matrix[i] = counter
        print(i, counter)
    
    matplotlib.pyplot.figure(figsize = (20,10))    matplotlib.pyplot.scatter(range(1, 10000), matrix[1:10000], s=1)

(Gotta love Python eh!)
