Does anyone know if it is possible to do clustering in the way that vis.js supports it with cytoscape.js? Here are some examples:

The basic idea is that a node can represent a cluster of child nodes and zooming or double clicking on the node will "explode" it to show all the children.

You can achieve the same effect using cy.on('zoom') with cy.add() and cy.remove(). That sort of feature would not be included in the lib proper, because it breaks graph semantics.
