Proper tools to analyze building skyline

Hi everyone, from five tools in Grasshopper, which one that I can use properly to analyze the skyline?
Thank you in advance.

Can you elaborate more on what you wish to analyze? Any performance metrics you have in mind that you would want quantify?

I mean, is it possible to analyze the visibility of building that viewed from the street using view analysis component? Then, from the output of a colored mesh that represents the visible part of the test geometry, can it be continued by calculating the fractal dimension?
