## Is the graph provided to NetworkX directed or undirected?

Which graph class should I use?

Networkx Class | Type | Parallel edges allowed |
---|---|---|

Graph | undirected | No |

DiGraph | directed | No |

MultiGraph | undirected | Yes |

MultiDiGraph | directed | Yes |

**Can undirected graphs have self loops?**

Graphs hold undirected edges. Self loops are allowed but multiple (parallel) edges are not.

### How do I add edges to NetworkX?

Add an edge between u and v. The nodes u and v will be automatically added if they are not already in the graph. Edge attributes can be specified with keywords or by directly accessing the edge’s attribute dictionary.

**Is complete graph NetworkX?**

We will use the networkx module for realizing a Complete graph. It comes with an inbuilt function networkx. complete_graph() and can be illustrated using the networkx. draw() method.

#### What type of graph is provided to NetworkX?

Which graph class should I use? ΒΆ

Graph Type | NetworkX Class |
---|---|

Undirected Simple | Graph |

Directed Simple | DiGraph |

With Self-loops | Graph, DiGraph |

With Parallel edges | MultiGraph, MultiDiGraph |

**Can undirected graph be acyclic?**

A forest is an undirected graph in which any two vertices are connected by at most one path. Equivalently, a forest is an undirected acyclic graph, all of whose connected components are trees; in other words, the graph consists of a disjoint union of trees.

## Is a connected undirected graph without any cycle?

An acyclic graph is a graph with no cycles. A tree is an acyclic connected graph. A forest is a disjoint set of trees. A spanning tree of a connected graph is a subgraph that contains all of that graph’s vertices and is a single tree.

**What is used to visualize NetworkX graphs?**

Option 1: NetworkX NetworkX has its own drawing module which provides multiple options for plotting. Below we can find the visualization for some of the draw modules in the package. Using any of them is fairly easy, as all you need to do is call the module and pass the G graph variable and the package does the rest.

### How do you create a complete graph?

A complete digraph is a directed graph in which every pair of distinct vertices is connected by a pair of unique edges (one in each direction)….

Complete graph | |
---|---|

K7, a complete graph with 7 vertices | |

Vertices | n |

Edges | |

Radius |

**What is a complete graph in discrete mathematics?**

A complete graph is a graph in which each pair of graph vertices is connected by an edge.

#### How is a graph stored in NetworkX?

NetworkX stores graph data in Python objects instantiated from one of several NetworkX classes. You choose the NetworkX class to use based on the type of graph you want to create. NetworkX graph classes include Graph, DiGraph, MultiGraph, and MultiDiGraph.
