AI overview
I cannot write an accurate overview based solely on the provided context, as it only contains an image caption and does not include factual information about what odor is or why it matters. To provide an accurate, evidence-based overview as you've requested, I would need substantive source material about odor itself.

An odor (American English) or odour (Commonwealth English; see spelling differences) is a smell or a scent caused by one or more volatilized chemical compounds generally found in low concentrations that humans and many animals can perceive via their olfactory system. While smell can refer to pleasant and unpleasant odors, the terms scent, aroma, and fragrance are usually reserved for pleasant-smelling odors and are frequently used in the food and cosmetic industry to describe floral scents or to refer to perfumes.
