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! answered Aug 22, 2019 by anonymous
