How to make graphs dealing with a column of frequency in R

I have this dataset of breast cancer

install.packages("vcdExtra")
library(vcdExtra) 
?Cancer
df_cancer<-as.data.frame(Cancer)

This data set is

Survival     Grade    Center Freq
   1     Died Malignant    Boston   35
   2     Surv Malignant    Boston   59
   3     Died    Benign    Boston   47
   4     Surv    Benign    Boston  112
   5     Died Malignant Glamorgan   42
   6     Surv Malignant Glamorgan   77
   7     Died    Benign Glamorgan   26
   8     Surv    Benign Glamorgan   76

I want to do graphs to view the supervivence ratio by grade and by center, but I don't know how to deal with the column of frequency because when I do a barplot or anything like that it counts the frequency in the dataset.

If you want the heights of the bars to represent values in the data, you can use geom_col with ggplot2

Here is an example with Cancer data

library(ggplot2)
ggplot(df_cancer)+
  geom_col(aes(x = Survival, y = Freq, fill = Grade), position = "dodge")+
  facet_wrap(~Center)

enter image description here

I'd rather be in Boston
