Service counts over time

This is just being nosy.

It would be interesting to see how many activities are imported per day of activity per source. And displayed graphically.

Obviously this would be dynamic as history keeps being imported from the various sources. But it would be a cool graph to see. (Being able to zoom in would also be useful.)

One thing this would show is how fast Garmin is adopted, and whether there’s a drop off in other sources because of this.
