I am trying to create a visual that nests four circles as so:
The size of the circle depends on a ratio/numeric value relative to the largest circle.
I found this post which seems to provide a solution for two aligned circles: Bubble Chart with bubbles aligned along their bottom edges
However, I am a complete newbie to R and not sure how to proceed to achieve the desired four aligned circles.
Sample input data:
d <- read.table(text = "circle:x Circle1:340000 Circle2:5000 Circle3:1100 Circle4:340", header = TRUE, sep = ":") Desired Output of four aligned circles based on input numbers:

Convert area to radius, then use ggforce to draw circles:
library(ggforce) #convert area to R d$r <- sqrt(d$x / pi) d$x0 <- max(d$r) / 2 d$y0 <- d$r ggplot(d, aes(x0 = x0, y0 = y0, r = r, fill = circle)) + geom_circle() + theme_void()
