People may complain about readability, but even with jpeg compression, extracting the data points is usually computationally feasible if there aren't too many of them.

Compact Graphs [Explained]

Transcript Under the Cut

[Left: graph of points plotted along two axes, headered by:]

Variable 1: X Axis

Variable 2: Y Axis

[A arrow pointing to the right.]

[Various semi-transparent numbers in different colors stacked on top of each other, headered by:]

Variable 1: Hue

Variable 2: Label

[Caption underneath:] Design tip: you can make your graphs more space-efficient by using hue and label for the first two variables, instead of only turning to them once you've used up the X and Y axes.
