Example

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

g.set_node_value('f', 3);
g.set_node_value('h', 21);
g.add('f', 'h');
g.set_edge_value('f', 'h', 100);

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

How can I use tiny-graph?
