Add explanation of variance partitioning? (feature request)

[benwhalley]

I really love the project and think it looks really pretty — I'll certainly be pointing students at this this year, so thanks.

I wonder if you'd be interested in incorporating a visualisation of variance partitioning too? I have attached a pdf of some images I use to try and show the split of within and between variance. They are not perfect by any means (notably, that the squares are shown from zero rather than the mean... I should fix that) but they do help students.

Thanks, @benwhalley -- I don't see the attached PDF -- could you try uploading again? I'd be excited to look through it.
