The bivariate analysis could be shown in terns oF stacked bar chart/ column chart/ dual axis bar chart.

1. Stacked bar chart - [ position = "stack"] - show proportion of each independent value of variable.

This chart shows 2 variables analysis in 1 axis.

Ex: 

ggplot(mpg, 
       aes(x = class, 
           fill = drv)) + 
  geom_bar(position = "stack") 

or

ggplot(mpg, 
       aes(x = class, 
           fill = drv)) + 
  geom_bar()

2. Side by side bar chart - [ position="dodge" ] - used for comaprison of 2 variables

Ex:
ggplot(mpg, 
       aes(x = class, 
           fill = drv)) + 
    geom_bar(position = position_dodge(preserve = "single"))

3. Filled bar chart - [ position="fill" ] - used to show proportion of variables.

Ex:

ggplot(mpg, 
        aes(x = class, 
            fill = drv)) + 
     geom_bar(position = "fill")

I found the examples and explanation about these examples from here 

Hope it helps!
