The first step in the Data Laboratory mode is obviously to get hold of some data. In Gephi, you can upload network data in the form of tabular data, in other words, as a spreadsheet.
In order to get started with this recipe, we will need some tabular data to work with. For this purpose, we will use the Hero Social Network Data.

In the first column of this row, insert the text Source and insert the text Target in the second column. These labels will act as headers while reading the file.
The following screenshot shows this dataset in Microsoft Excel 2013:
