How to Put Dots on Sphere Mesh Node Points?

I found those codes for drawing a sphere. I can get the x,y,z coordinates.
I would like to use those x,y,z coordinates. But I don't want to color the sphere by using the surf command. In state, I want it to leave the sphere blank by only with the mesh lines. Then I want to plot a single point on each mesh nodes according to radius. There would be dots on each mesh nodes. And the radius of the dots would be varying by z coordinates. For example, for the downside, the dots would be small, on the upside the dots would be bigger.
[x,y,z] = sphere; %# Makes a 21-by-21 point sphere
x = x(11:end,:); %# Keep top 11 x points
y = y(11:end,:); %# Keep top 11 y points
z = z(11:end,:); %# Keep top 11 z points
r = 1; %# A radius value
surf(r.*x,r.*y,r.*z); %# Plot the surface
axis equal; %# Make the scaling on the x, y, and z axes equal

Try this (replacing the surf call):
figure
scatter3(r.*x(:),r.*y(:),r.*z(:), 0.001+z(:)*100, 'o', 'filled'); %# Plot the surface
axis equal; %# Make the scaling on the x, y, and z axes equal

Added plot figure:
