#### Example Graphs ----

# Hi STAT 385 @ UIUC Spring 2019

# Create a scatter plot
ggplot(mpg, aes(class, hwy)) + 
  geom_point()

# Plot a jittered scatter plot
ggplot(mpg, aes(class, hwy)) + 
  geom_jitter()

# Create a box plot
ggplot(mpg, aes(class, hwy)) + 
  geom_boxplot()

# Combine both!
ggplot(mpg, aes(class, hwy)) + 
  geom_jitter() + geom_boxplot() 

# Another popular way of a similar visualization
ggplot(mpg, aes(class, hwy)) + 
  geom_violin()

# Split data based the type of class it is.
ggplot(mpg, aes(displ, hwy)) +
  geom_point() +
  facet_wrap(~class)
