Proper way to set up a dynamic map-reduce graph in Strands?

[Nicricflo]

I would like to understand the proper way to set up a map-reduce graph framework in Strands. I am used to using the Send api from langgraph (see https://docs.langchain.com/oss/python/langgraph/graph-api#send for reference).

Basically, at runtime, depending on the users query, I would like anywhere from 1-5 sub-agents to be spawned (depending on user query complexity) to perform various tasks (in parallel). What would be the best way to accomplish this with strands?
