"dependencies": [4, 5, 6]
}, {
"label": "leave",

}, {

"dependencies": [8]
}, {
"label": "wake up",
"dependencies": []
}
]
Include d3.topological.js and:
d3.json('data.json', function(nodes) {
// The data is given as shown above.
// The algorithm adds a number property to each node.
// The number represents the position of the node in the topological sort.
var topological = d3.topological()
.nodes(nodes)
.sort();
// The nodes can now be sorted using their number.
d3.ascending(nodes, function(a, b){ return a.number - b.number; })
});
