[Feature Request] Option to scale file nodes based on number of lines

[Namingwaysway]

It would be very valuable to understand the relative size of some of the files. I would really like an option to adjust the file diameter based on the number of lines in the file. It seems possible to generate through the difflog [Keep a running total of added/deleted]. There might also need to be a scaling option, to adjust how the lines of code affect the diameter.

Sounds like a duplicate of #91.
