How to manipulate cytoscape.js graph data before rendering

I have relatively big amount of graph data (over 1000 nodes, over 2000 edges). Cytoscape.js is failing to render this amount of data, so I decided I will cook some interactive graph exploration. I want to start with graph roots (it is DAG) and user will be able to explore nodes after clicking on them.

I know I can do it outside of cytoscape.js, but I wanted to know if I can create a node/edge collection that I would manipulate (remove all nodes but roots and their neighbours) and then use as data source (get child nodes of nodes). Cytoscape makes graph processing quite easy and it would be great to not need to reinvent the wheel.

I tried creating cy.collection based on the JSON data I was feeding to the graph, but it seems like it doesn't accept the same data format as cy.load.
