I'm trying to draw a circle using simple vertices points and a big gl_PointSize value. I found this example and try to reproduce it on WebGL with no success.

This is just using regular old sine and cosine to step around the circumference of a circle and place points. You just need to know the center of the circle, the radius and how many points you want. The following pseudo code will output a set of points that make up the positions of dots you need to make a circle of points:
You will have to modify it to fit your language and APIs. But, if you know how to draw a point, you can easily utilize this to know where to draw them.
