```
ggplot(data=response, aes(x=beak_size, fill=generation)) 

```

This is my code so far, I keep getting a barely readable graph, and when I've tried to make my histogram using basic R I keep getting this error for the following code:

```
hist(response$beak_size, col="lightblue",
     main="Graph",
     xlab="Beak Size", ylab="Count")

Error in hist.default(response$beak_size, col = "lightblue", main = "Graph",  : 
  'x' must be numeric

```
