AI Drawing Prompt Reference
Create a scatter plot and display a best fit line, also label the correlation coefficient, to demonstrate the relationship between linear regression and data distribution analysis. Start by plotting the scatter data, then fit a best fit line based on the data, and finally calculate and label the correlation coefficient to show the strength of the linear relationship between the data points.
