I have been stuck on this for a while and I would like some help if possible!
The goal: I want to group the data by year using dot plot. I always want the size of the dot to represent the number of values.(Something like a propotional sized dot mark). Iv tried group transform but that doesnt seem to work.
Iv used d3.nest to group the data by year. The challenge is turning that into a dot mark plot…
If you have any suggestion, I would be grateful. Thank you!
