You can do this a bit more easily with:
VADeaths_flat_df <- melt(VADeaths)
names(VADeaths_flat_df) <- c("Age", "Person", "Data")
> bin_size<-15.0

Those plots look fine to me (well they're what I'd expect from the
definition), but I'd think you'd want
ggplot(VADeaths_flat_df, aes(Data, fill = Person)) +
geom_histogram(binwidth=20)
or maybe
ggplot(VADeaths_flat_df, aes(Person, weight = Data)) + geom_bar()
ggplot(VADeaths_flat_df, aes(Person, weight = Data, fill = Age)) + geom_bar()
