# Course Goals

* Develop intermediate data management and visualization skills in R

* Learn basic programming

# Univariate Graphs

## Categorical variables

--
+ The distribution of a single categorical variable is typically plotted with a bar chart, a pie chart, or (less commonly) a tree map.
---

# Bar Charts:

--
  + The Marriage dataset contains the marriage records of 98 individuals in Mobile County, Alabama. Below, a bar chart is used to display the distribution of wedding participants by race.
  
--

```r
library(ggplot2)
library(mosaicData)
data(Marriage, package = "mosaicData")

# plot the distribution of race
ggplot(Marriage, aes(x = race)) + 
  geom_bar()
```
