custom avatar random walk

I'm coding a scene where I have an animation of a spiderwalkcycle. It's moving up, down, left and right very well.
But that's not what I want.
What I want to do is a spider that is walking to random points. Those points have to be around a certain centerpoint because I have to be able to move that centerpoint.

I know it's a rather advanced question but I don't get it to work.
Does anyone has an idea how I have to code this?

Thank you

I've attached a script that generates a set of random points around a center point within a certain radius. You can use the GenerateRandomPoint(x,y,radius) function in your script. Just pass it the center point and radius and it will return a 2D point within the circle. Hope this helps.
Code:
import viz
import math
viz.go()

def GenerateRandomPoint(x,y,radius):
	r = vizmat.GetRandom(0,radius)
	a = vizmat.GetRandom(0,2*math.pi)
	return math.sin(a)*r + x , math.cos(a)*r + y
	
viz.startlayer(viz.POINTS)
for x in range(1000):
	x,y = GenerateRandomPoint(0,1.8,1)
	viz.vertex(x,y,5)
viz.endlayer()
