Show HN: Real-time 4/20 cannabis sales dashboard using Estuary and Tinybird

[sv123]

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.

How did you get access to the data?

[sv123]

Point of sale APIs.

Cool map, I'd speed it up a bit though

FYI, the time displays are a bit off. The time box seems correct. The time slider is off. The animation goes beyond the last time. Up to you if the slider stops in the middle, or goes to 100% which becomes larger as the day progresses

> I'd speed it up a bit though

Clearly not partaking in 420 ;-)

[dehugger]

The clock in your map covered the entirety of the section I actually wanted to see.

[Babkock]

Cannabis?? Such a racy controversial topic... I don't know if I can talk about... Marry wanna... the debble's lettuce

[LightBug1]

Cool analysis ... but 420 has been made so cringe now ...

[hsuduebc2]

Are you referring to marihuana as a substance or to the 420 as an symbol of it?

[accrual]

Could you elaborate on what you mean?

[ivape]

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

[lpa22]

Alcohol is significantly more harmful and dangerous to the body than weed. If anything, this is incredible progress and a much longer way to go.

[MisterTea]

The irony is my hippie uncle hates how legalization took away a lot of the culture surrounding weed in terms of bonding over the illegally and cooperatively hiding each others "bad habits."

[sv123]

What is the scary part?

[kstrauser]

There are more liquor stores than weed stores near me. We've decided as a society that it’s OK to have liquor stores all over the place. It’s wild to me to fret over the far fewer numbers of dispensaries.

Yeah, weed is probably bad for you, given enough of it. It turns out there's no safe dose of alcohol, and no one’s figured out where weed’s harm eventually kicks in, so why worry about its societal effects which we know are vastly lesser?

I drink beer and don't use weed. All of the above is from someone who couldn’t care less about marijuana for themselves.

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.

There seems to be a high density of marijuana storefronts in my city.

I'm wondering who, angry and scared about the state of society, is checking out, rather than speaking out.
