how to plot a cute sphere

hi. i tried to plot a sphere with sphere function. but the sphere was very ugly. and it was more like an ovoid. plz help me to plot a nice sphere. something like this pic

a=[0 0 0];
[e,f,g] = sphere(30);
e=e*0.3;
f=f*0.3;
g=g*0.3;
s1=surf(e+a(1),f+a(2),g+a(3),'FaceAlpha',0.2,'FaceColor','r')

I am achieved upto this level, see here

[x,y,z]=sphere;
hSurface=surf(x,y,z);
set(hSurface,'FaceColor',[0 0 0],'FaceAlpha',0.3,'FaceLighting','gouraud','EdgeColor','none')
camlight
axis equal
axis off

If you don't have access to the cuteSphere toolbox, you can just use this line of code below to make the sphere appear as a sphere.

%[your plotting code] 
axis equal

The reason your sphere appeared as an ovoid is because the data aspect ratio is not equal.
