I would create the visualization in Kibana and then save it, then you can look at how they did it. Which would provide you a quick example of how they do it.  
To view just go to Kibana-\>settings-\>objects-\>visualizations and find the vis you saved

Each Aggregation works a little differently , and reading up on it would be a good start.
