# Correlation plot

R offers other ways of displaying the correlation matrix. With the `corrplot`

package, the visualization of correlations is made easier and more powerful by allowing you to represent the correlations with numbers, symbols, colors, and more.

In this exercise, you will use the provided correlation matrix `cor_mat`

and the `corrplot()`

function to draw some correlation charts.
