I'm trying to plot a histogram and fit a bell curve. I got different measurements in diameter and group by gender. I'm not sure how to fit a bell curve. My code for the histogram is the following.

body %>% histogram(~ diameter|gender, col="dodgerblue3",
                   layout=c(1,2), data=., xlab="Diameter")

Here is a sample of my data. The file I've saved as is body.csv.

Diameter	Gender
31.5	Male
34	Male
33.2	Male
32.3	Male
31	Male
34	Male
31.5	Female
34	Female
33.2	Female
32.3	Female
31	Female
34	Female

Please use ```dput()``` and produce a sample of your data frame. – Shibaprasadb Aug 29 '21 at 08:00
It does not show how to do it by group – manavhs13 Aug 29 '21 at 09:00
Do you want to add a density plot of your data or a fitted normal distribution? – Martin Gal Aug 29 '21 at 09:19
I want the histogram with the normal curve. – manavhs13 Aug 29 '21 at 09:26
