Why do my nodes overlap each other

Hello -

After plotting a graph using 'force' layout, and gravity on, I need to hightlight some nodes by increasing their size. They then overlap or cover neighbourhing nodes. I do not want this, I want to be able to see all nodes distincly. Is there a way to ensure all nodes are distinct and non-overlapping?

Thanks.

Hi,

Can you share a image of the plot ?
