tiny-graph

Tiny graph data structure for Client or Server

Example

const graph = require('tiny-graph'),
    g = graph();

g.setNodeValue('f', 3);
g.setNodeValue('h', 21);
g.add('f', 'h');
g.setEdgeValue('f', 'h', 100);

console.log(g.adjacent('f', 'h')); // true
console.log(g.neighbors('f')); // ['h']
console.log(g.getEdgeValue('f', 'h')); // 100

How can I use tiny-graph?

tiny-graph can be installed from npm & bower, and supports AMD loaders or script tags (window.graph).

fromJSON(arg)

Deserializes arg as the graph

getEdgeValue(x, y)

Returns the value associated to the edge (x, y)

getNodeValue(x)

Returns the value associated with the node x

neighbors(x)

Lists all nodes y such that there is an edge from x to y

setEdgeValue(x, y, v)

Sets the value associated to the edge (x, y) to v

setNodeValue(x, v)

Sets the value associated with the node x to v

toJSON()

Serializes the graph as JSON
