Off topic:What Software To Use To Make A Clonal Evolution In Cancer Figure?

Question

[Wayne]

Hello all,

I am trying to generate a figure very similar to this one : http://genome.wustl.edu/image/images/sections/publications/aml_relapse_cover_v1-draft8-cropped.jpg for my cancer data. Any ideas on how it was created? The paper methods don't provide any information.

Thanks!!
