Exercise

Visualizing attributes

In this exercise we will learn how to create igraph objects with attributes directly from dataframes and how to visualize attributes in plots. We will use a second network of friendship connections between students.

Instructions

100 XP

Create a new igraph object with graph_from_data_frame(). Two dataframes need to be provided - friends1_edges contains all edges in the network with attributes and friends1_nodes contains all vertices in the network with attributes.
View all edges where the attribute hours is greater than or equal to 5 hours.
Create a new vertex attribute containing color names: "orange" for females and "dodgerblue" for males.
Plot the network with vertices colored by gender and make label names "black".
