Show unique values on bubbles graph in R - r

Question

I'm working with a db which looks more or less like this:
dput(ex)
structure(list(clave = c("01", "02", "03", "04", "05", "06",
"07", "08", "09", "10", "11", "12", "13", "14", "15", "16", "17",
"18", "19", "20", "21", "22", "23", "24", "25", "26", "27", "28",
"29", "30", "31", "32", "33"), n = c(2127, 3519, 153, 2070, 3089,
2971, 3005, 152, 53409, 2351, 4599, 3121, 4828, 7588, 25714,
4218, 3032, 295, 3856, 3885, 7044, 3246, 2589, 2559, 2223, 2316,
3560, 2695, 2465, 6742, 4024, 2065, 1627)), row.names = c(NA,
-33L), class = c("tbl_df", "tbl", "data.frame"))
And I'm using the packcircles package to create a bubble graph for just one variable since standard bubbles are added as a third dimension on ggplot. I'm using paletteer library too:
library(packcircles)
library(paletteer)
Next code creates the data.frame that will be used on the graph. First I create the coordinates for the bubbles (circles) and then I incorporate my clave and n variables from original data.frame:
# Create circles
ex_ <- circleProgressiveLayout(ex$n)
ex_ <- circleLayoutVertices(ex_, npoints=50)
# Incorporate variables
ex_$clave <- rep(ex$clave, each=51)
ex_$n <- rep(ex$n, each=51)
# Palette
colors <- paletteer_c("ggthemes::Green-Gold", 33)
Now we're ready to graph:
ggplot(data = ex_, aes(x, y, fill=clave)) +
geom_polygon() +
coord_fixed(ratio = 4/5) +
theme_void() +
scale_fill_manual(values = rev(colors)) +
geom_text(size = 3, label= unique(ex_$n))-> my_graph
plotly::ggplotly(my_graph)
Code above throws following error:
Error in `check_aesthetics()`:
! Aesthetics must be either length 1 or the same as the data (1683): label
Run `rlang::last_error()` to see where the error occurred.
If I use instead:
ggplot(data = ex_, aes(x, y, fill=clave)) +
geom_polygon() +
coord_fixed(ratio = 4/5) +
theme_void() +
scale_fill_manual(values = rev(colors)) +
geom_text(size = 3, label= ex_$n)-> my_graph
plotly::ggplotly(my_graph)
Now every circle is surrounded by text (51 times same text). What I want is that only clave and one value of n were showed when you pass the mouse pointer through each circle.
Any advice or idea to handle with this will be much appreciated.

How about this. The mouse-over doesn't work in the static picture below, but if you run the code, it should.
ex <- structure(list(clave = c("01", "02", "03", "04", "05", "06",
"07", "08", "09", "10", "11", "12", "13", "14", "15", "16", "17",
"18", "19", "20", "21", "22", "23", "24", "25", "26", "27", "28",
"29", "30", "31", "32", "33"), n = c(2127, 3519, 153, 2070, 3089,
2971, 3005, 152, 53409, 2351, 4599, 3121, 4828, 7588, 25714,
4218, 3032, 295, 3856, 3885, 7044, 3246, 2589, 2559, 2223, 2316,
3560, 2695, 2465, 6742, 4024, 2065, 1627)), row.names = c(NA,
-33L), class = c("tbl_df", "tbl", "data.frame"))
library(tidyverse)
library(packcircles)
library(paletteer)
ex_ <- circleProgressiveLayout(ex$n)
ex_ <- circleLayoutVertices(ex_, npoints=50)
# Incorporate variables
ex_$clave <- rep(ex$clave, each=51)
ex_$n <- rep(ex$n, each=51)
# Palette
colors <- paletteer_c("ggthemes::Green-Gold", 33)
ex_ <- ex_ %>%
mutate(lab = paste0("clave: ", clave, "\nN: ", n))
ggplot(data = ex_, aes(x, y, fill=clave, text=lab)) +
geom_polygon() +
coord_fixed(ratio = 4/5) +
theme_void() +
scale_fill_manual(values = rev(colors))-> my_graph
plotly::ggplotly(my_graph, tooltip = "text")
