Built this dashboard to visualize cannabis sales in real time across North America during 4/20. The data updates live from thousands of dispensary POS transactions as the day unfolds.

Under the hood, we’re using Estuary for data streaming and Tinybird to power super fast analytical queries. The charts are made in Tremor and the map is D3.

Walk-in sales indicate these stores are everywhere. It's kind of scary to be honest.

At 7:40 today (Sunday) there was a line outside the dispensary in my town, presumably waiting for it to open. People are really in love with it.

But why do they need to buy it on that particular day? They could buy it on any of the other days of the week. I am guessing the most popular day might be Friday.

I'm not convinced that there isn't a line every Sunday.

It was the trifecta of high holy days (Passover, Easter, 4/20).
