I am a fresh man for the force-directed figure. And I recently plot such figure under the requirement of reviewers. However, I don’t know how to explain the bar and spot in the figure: what’s the meaning of the thickness of the bar connecting two circles; what’s the meaning of the circle size?
Here I post a example figure with 3 cell types, “S”, “G1”, and “G2M”. Could you please explain this figure?
