Displaying large networks with cytoscape.js -

i'm trying use cytoscape.js display large networks hundreds of nodes. however, cytoscape.js seems want constrain viewport, can problematic if there many nodes crowding viewport. i'm using "arbor" layout , during force-directed simulation nodes don't seem exit viewport's initial boundaries, if zoom out @ initialization. setting arbor's fit option false doesn't seem anything. preferred way go displaying large networks in cytoscape.js?

there other layouts can use. i'll issue arbor, though https://github.com/cytoscape/cytoscape.js/issues/307
