For the graphs of the home price / bathroom data set, what does the vertical axis represent? I don't see it labeled or discussed anywhere.

I just took the index of the data point (i.e. 1, 250) as the y-axis with the intention of "Stretching out" the data set along the y-axis. Otherwise the data would otherwise be illegibly compressed on a 1-D number line.

In retrospect, I could have better represented the data with 2 overlying histograms, but this (somewhat) captures the intent of showing that "more expensive houses tend to have more than 2 bathrooms".

I agree with you that 2 histograms would be better. Check out the grouped barchart on this link
