Overlapping edges

The two fundamental building blocks of a social network are nodes and edges. The weights are usually positive values.

The dataset edges contains the edges for a small network. Multiple edges between two nodes in the network could indicate a stronger link between the nodes compared to only one edge between the nodes. Instead of showing each edge individually, you can make the edges overlap where the width or weight is equal to the number of edges.

The igraph library is loaded in your workspace, as well as the dataset edges.

Create an undirected graph net based on edges with graph_from_data_frame().
Plot the network net and set the layout to be a circle.
To get overlapping edges, set E(net)$width to the number of multiple edges using count.multiple(). Use a boolean to avoid having curved edges.
Have a look at the new edge attributes and plot net in a circle layout again.
