Thanks! It's a neat visualisation, so I was curious to see if it was something you'd cooked up yourself. A couple of times I've experiemented with exporting my data from Apple Health to create my own data visualisations. I still get tempted now and then to whip up something in Python that spits out charts using something like matplotlib, but getting Apple Health data off the phone is a complete PITA. Unless I want to build an iOS app that implements HealthKit, I have to manually export the data to a file.
