MORE UNDERSTANDING ON CODES

I got some ideas how these codes works, so I started to tweak as my pleasant.
At the very first, I tried with filtered random, tried to fix some numbers to get more interesting results.

 Comment :  Crazy waves caused from filter and random. Interesting.
CODE :
------------------------------------------------------------------------------------------------------------------
XRES = 600
YRES = 400

def setup():
    size(XRES, YRES)
    background(255)
    stroke(0)
    smooth()
   
randata = []
for i in range(XRES):
    randata = randata + [random(-50.,150.)]
   
def plot(data, yoff):
    for i in range(1, XRES):
        line(i-1,yoff+data[i-1],i,yoff+data[i])
       
def filter(data):
    for i in range(1,XRES-1):
        data[i]=0.5*(data[i-1] + data[i+1])
       
def draw():
    filter(randata)
    if (4*frameCount)<(YRES+100):
        plot(randata, 4*frameCount)

What if I tried with another shapes instead of using lines? Here with the circles

Comment : Looks crazy, I love this.
 CODE :
------------------------------------------------------------------------------------------------------------------
 XRES = 600
YRES = 400

def setup():
    size(XRES, YRES)
    background(255)
    stroke(0)
    smooth()
  
randata = []
for i in range(XRES):
    randata = randata + [random(-200.,200.)]
  
def plot(data, yoff):
    for i in range(1, XRES):
        ellipse(i-1,yoff+data[i-1],i,yoff+data[i])
      
def filter(data):
    for i in range(1,XRES-1):
        data[i]=0.5*(data[i-1] + data[i+1])
                          
      
def draw():
    filter(randata)
    if (40*frameCount)<(YRES+100):
        plot(randata, 40*frameCount)

And trial with rectangle

Comment : Hierarchy indeed, but not my types of art. Good trial to understand more on codes though.
