love your visualizations @krstoffr - but this http://rpsychologist.com/d3/correlation/  implies a bit that corr relates to slope of line of best fit...?

thought about using it for teaching - but found it's a common misconception that slope ~ corr and i'm afraid the visualisation might

strengthen this? unless I am completely mistaken?! obviously, could manually move data points... but too lazy...

any chance you could implement moving the fitted line & data points for one corr coeff, too? :)

I can make one later today that shows this. See also my collection here: http://emilkirkegaard.dk/understanding_statistics/ … All made in Shiny with public code. :)

that would be very neat! and thanks - will definitely check them out!

I usually show this manually by dragging a point so var(y) increases, correlation decrease, while slope is the same.
