My visual was constructed using mtcars data using R studio.
Correlation Analysis has been somewhat troublesome. Creating and interpreting the outcome has been challenging for me.
The visual shows decreasing correlation between cylinder and mpg on the mtcars data.
In my opinion, the visual is easy to read as it shows how the information decreases going right. The red line on the visual makes it easier for the audience to understand what the image is trying to interpret. The shadow on the red line also makes it easier to read.
