Is it a good idea to connect data points on a plot to increase readability in slides? I have a graph of points from a set of experiments,
that I want to present on a slide.
The important information in the graph is both the values of the points,
and more significantly, that the green points are above the blue points.

It is quick and easy to get my plotting framework (matplotlib)
to connect each point to the next:

It should be fairly clear to anyone that the relationship between points is not expected to be linear.
I thought I could want to put the line in to make it clear that one is below the other. It can be hard to see the point markers on the projector screen.
Is this a good idea?
Does showing plots this way enhance the visibility of the them for presenting, or does the fact the that lines themselves are fairly meaningless distract too much?
Audience  concerns:
The whole presentation is for graduating engineering students and must be simple. While they would normally have the capacity to deal with complicated plots, the content of the presentation is complicated enough that I don’t want to distract them with anything that might waste thought time. I have already rejected the box-and-whiskers plot as too complicated; this is a plot of the mean values of that data.
Drawing the lines implies a continuous relationship between the parameters. So if you can expect continuity, then connecting the points is fine. A second point to make is to avoid colours that are as similar as the green and blue you have chosen. One reason the difference is hard to see in the first scatter plot is due to colour. Try to experiment with colours that contrast better and your problem may be solved by just altering colours for one or both of the data sets.
