A basic scatterplot with variable axes. Uses d3’s update pattern to modify the axis values as well as the x y position of the points on the plane.
A linear regression is then calculated and plotted for the data set being visualized. The slope, y-intercept and rSquared values are calculated from code found here: http://bl.ocks.org/benvandyke/8459843
A random generator is then used to fetch an x value, plug that into the y=mx+b format and give an array of points which, when plotted, aproximates the linear regression. The transition on the linear regression is a bit wonky, I stil need to look into that, feel free to comment if you know where I went wrong there.
