Welcome back. Hopefully, you enjoyed creating sketches to help determine the story we’ll be communicating to our users. Let’s take a look at my solutions.

Vocabulary
- Choropleth map: a map created by coloring in existing geographic regions based on the relative frequency of a variable.
- Scatter plot: a chart that displays the values of two different variables as points so we can study the correlation between the variables.
- Outliers: data points that don’t fit the general pattern.
- Line chart: a chart that shows the change of data over a continuous time span. Line charts show trends or changes in value.

In this map, a state like New Mexico
with 20.2 deaths per 100,000

people would be much darker in color
