Manipulating the nodes in a graph is one of the fundamental operations of a graph. One such operation is adding a new node to the existing graph. In this recipe, we will learn how to carry out this operation in Gephi.
In order to understand how to add a new node to the existing graph, we will start with an empty new project and then progressively add nodes to the new network. So, start Gephi and load a new project from the welcome screen.
To add a new node to a new or an existing network, follow these steps:
Go to the Data Laboratory mode in Gephi.
Click on the Add Node button in the top panel. This opens the Add node dialog window, as shown in the following screenshot:
In the Label textbox, enter the name that you want to give to the new node. Once entered, hit OK. This creates a new node in the network with a user-specified label. The following screenshot shows the spreadsheet view of the network in Gephi with the new node labeled...
