Do you need labels and titles for scatterplot?

A scatterplot on paper needs labels (numbers) and titles on both axes; the xand yaxes typically won’t start at 0. Here’s the plot for this data set. (The horizontal lines aren’t needed when you plot on graph paper.) When the same (x,y) pair occurs multiple times, plot the second one slightly offset.
