These are the great and intuitive visualizations to understand the logic
of regression and collinearity. Thanks for the post!

This is great and what I have been looking for (also for teaching). I
sometimes wonder whether squares would be easier to understand (because
the edge length could be the empirical standard deviation?) but I
presume overlapping those looks messy. Thanks!

Thanks. This is helpful at the same time to both novices and to experts.

Really appreciate your clear illustration! I followed your R-code and fully understood the whole process!!! Thank you sooooo much!!!!
