How to interpret graph result of jmeter load test?

I am running a test with jmeter on osx against a server cluster. Now I am wondering how to interpret the test results taken with "graph result".

This is an example output running 50 threads on a macbook pro 2015:

It states 2,090.949/minute throughput. Is this 2M requests per minute? That would equal 33K/s ?! The y-Axis indicates ms, is this latency or time for each request? What do the numbers Average, Median etc. indicate, are those ms per request?

Thank you for any help on this.
