Rabbit L-Systems - Data Tree - Scaling...Need Help!!!

Hello All,

I'm working with Rabbit L-Systems to create a branching structure. Now that the primary structure is created i want to vary the thickness of the limbs as the structure grows, such that it is thickest at the base.

When i use simple series + scale, i do not get the desired output (see attached). I have tried grafting and flattening the output before applying scaling.

However, it seems to be more complex than that. If I'm not mistaken, this may be achieved by taming the data structure. I'm not a pro at it. Can some-1 help me please?

I have attached the design representation and GH Definition for reference.

cheers
