A network is a system of connected elements:
There are 3 kinds of a network: directed, undirected, mixed.
Think about: why visualize, which elements, what are the relationship between the elements Gather (if there are) the different data sources
Rename the cells A1: Source, B1: Target, like so
Please note: use always the same text for each element. We can’t use the instagram URL and the username for the same entity. Otherwise there will be displayed two different nodes of the same entity/account.
