How do I create a parametric relationship (ratio) between circles in a grid so that the circles get small or larger along the u and v direction. I have set up the circles in a grid with a controllable number slider related to the number of rows and columns, but I am struggling to set up a ratio relationship between the circles.
May anyone be able to help?
Please see attached the the video for what I’d like to achieve.

I already did it but can’t find the discussion !!!
It is very basic Math, so if you are more than say 15 years old, it is a good Math/Grasshopper exercice

Width = number of circle * radius 2=> radius = Width/(number of circle2)
Number of circle = row number + initial number of circle (-1)
height = sum of circle radius *2(use Mass Addition in Grasshopper)

Thanks, I still don’t fully understand how to apply this in grasshopper terms, could you show a solution in grasshopper if possible.
Kind regards,
Anna

For sure it requires some iteration so it is a bit tricky in Grasshopper, you have to use Mass addition.
But please try to take a pencil and a paper and write the equations. It is what I do at the moment.

Hi Laurent,
Okay, thanks we’ve set up the uv parameters and set the circles within a box, but struggling to set the ratio relationship between circles. May you offer some more direction please.
