Description

This project provides a Graph class that works for Node.js.

Creates an Graph data structure with basic functionality, add vertex/edge allowing nodes of any type.

Graph constructor

  • require('undirected-graph') creates an empty graph

Graph methods

  • addEdge(A, B) returns the value stored for that key.
  • toString() returns the associations between nodes (connected neighbours).
  • getVertices() returns the vertices in the graph

Examples

Assume this for all examples below

var graph = require('undirected-graph');

If you're using this within Node, you first need to import the class

var graph = require('undirected-graph');

var graph = require('undirected-graph');

Map size / number of elements

var graph = require('undirected-graph');
 
graph.addEdge(1, 3);  
graph.addEdge(1, 4);  
graph.addEdge(1, 5);  
graph.addEdge(2, 3);  
graph.toString();
 
 
//Graph associations (connected neighbours).
