A few days ago, we were asked what was the greatest number of simultaneous workshops we’d ever run. I didn’t know, but it was an easy enough question to answer from our records:

Simultaneous workshops over time

I’m sure better visualizations are possible (if you want to create one, the raw data is here), and we should find some way to show that the burst starting in April 2014 is actually a couple of workshops that were spread out over several weeks, but I think the trend line is pretty cool.
