Scatter plot / regression line

It would be nice to have a scatter plot / regression line instead of a line graph that connects all points. Sometimes it is nearly impossible with the current solution to see any trend in the data if the points vary a lot.

I'm not really familiar with the available statistical instruments and plot types for this. I think plotting all points will still yield a lot of completely colored areas with that many workers. Maybe some form of configurable pre-aggregation of values would improve the usefulness of these graphs (think a graph that connects averages over five seconds, which should be less volatile).
Before we implement something, we should discuss our options. @joh-mue, can you research and present some options as basis for deciding this?

will do

Works with:

-s, --smoothing ALGORITHM        Smoothes the graph using the given algorithm.
-a, --average-over SLICE_SIZE    Calculates the average for slice_size large groups of values.
