AI Drawing Prompt Reference
Create a scatter plot showing the distribution of data points, calculate and display the correlation coefficient and the line of best fit with its equation. Allow dynamic updates to the correlation coefficient and the best fit line as the points are moved, and label the correlation coefficient value and the coefficients of the fit line equation.
