Building segments bar graphs

"What is the probability that a person in excellent health suffers from depression?" and "Are depression rates lower for healthier people?" are questions we can start to answer by adding conditional proportions to tab_DH and creating a segmented bar graph.

Notice that we need to use ungroup() in our data wrangling below.
