Normal dynamic fog-of-war sudoku rules apply.
A digit in a square indicates the total number of digits it sees in its row and column which are smaller than itself, where digits larger than itself block vision. (For clarity, it does not see itself.)
Digits either side of a black dot have a ratio of 1:2.
Solution code: Column 7

Very nice! Slow but fun and rewarding solve until the end, where a surprise, which I found a bit unfitting to the puzzle, completely rushed it to the end. Thank you

Great puzzle, very interesting rule (see comment below from Imdemasi so you don't misinterpret them like I did for the first 20 min :)). Loved it. Thanks!

Great puzzle. Really interesting deductions to be found with how the squares interact.

Can you clarify the vision rule? eg If a digit 4 is in a square and the digits to the right of it are 2 3 1, does it see all of those digits, or does the 3 block vision of the 1?
---
Only digits larger than 4 would block vision, so it would see the 1
