Modify the following plot to change the color of all points to "pink".

ggplot(starwars, 
       aes(x = height, y = mass, color = gender, size = birth_year)) +
  geom_point(color = "pink")

Warning: Removed 51 rows containing missing values (geom_point).

Add labels for title, x and y axes, and size of points. Uncomment to see the effect.

ggplot(starwars, 
       aes(x = height, y = mass, color = gender, size = birth_year)) +
  geom_point(color = "#30509C") +
  labs(
    #title = "___",
    #x = "___", 
    #y = "___",
    #___
    )

Warning: Removed 51 rows containing missing values (geom_point).

Pick a single numerical variable and make a histogram of it. Select a reasonable binwidth for it.

(A little bit of starter code is provided below, and the code chunk is set to not be evaluated with eval: false because the current code in there is not valid code and hence the document wouldn’t knit. Once you replace the code with valid code, set the chunk option to eval: true, or remove the eval option altogether since it’s set to true by default.)

ggplot(starwars, aes(___)) +
  geom___

Pick a numerical variable and a categorical variable and make a visualization (you pick the type!) to visualization the relationship between the two variables. Along with your code and output, provide an interpretation of the visualization.

Interpretation goes here…

Pick a single categorical variable from the data set and make a bar plot of its distribution.

Pick two categorical variables and make a visualization to visualize the relationship between the two variables. Along with your code and output, provide an interpretation of the visualization.

Interpretation goes here…

Pick two numerical variables and two categorical variables and make a visualization that incorporates all of them and provide an interpretation with your answer.

(This time no starter code is provided, you’re on your own!)
