in Barcelona, CT·counted·69 all time
A chemist or chemistry-related shop, typically displaying laboratory equipment, scientific supplies, medicines, or chemical products.
Counted, not streamed: Chemist has no time series, so it is read as a footprint across places. All-time count by city.
Things that physically exist: street furniture, signs, buildings. All-time counts.
