Bar Chart Wide and Borders

ds %>%
  ggplot(aes(wind_dir_9am)) +
  geom_bar(width=1, colour="blue", fill="grey") +
  scale_y_continuous(labels=comma) +
  labs(x=vnames["wind_dir_9am"], y="Count")

We can improve the appearance of a fat bar chart by adding, in this case, a blue border to the bars, using colour="blue". By itself that would look a bit ugly, so we also fill="grey" the bars with grey rather than the default black. We can play with different colours to achieve a pleasing and personalised result.
