How to make a marker circle bold?

Below is my command to make a simple plot. How do I make the circle line of the marker bold without making the circle bigger?

plot(x, y, 'ro');

Thanks.

plot(x, y, 'ro', 'linewidth',2);

You can make the linewidth greater than 2 if you want more bolding.

Interesting. I thought linewidth is for the lines connecting the markers only.
