Quality of five colloquial complex trend queries and their explanation. Five different

colloquial queries (not copies!) that represent trend queries must be listed (at least) and

described in detail. A trend query can be recognized by the fact that (i) the graphical

visualization of its result is a diagram with a time unit at its x-axis and a numerical unit at

its y-axis, (ii) the trend is represented as a smooth curve, and (iii) each (time, number)-pair

of the trend curve is a computed value.

please give me 5 queries of examples with graphical representation on any topic.
