visual analytics based on correlation

In this week assignment i was allowed to create my own visual analytics based on correlation using data "mtcars" from rstudio database. I first import the data into rstudio and then correlate using "cov(mtcars, use="complete.obs")" which format cor(x,y) to generate correlations between the columns of X and the columns of Y. I also use a scatter plot matrices to determine if the linear correlation between multiple variables is comparable.
