The code will depend on how you've chosen to represent the graph in the csv file. The attached assumes the file is a list of pairs representing edges.

SetDirectory[NotebookDirectory[]];

importedEdges = Import["edges.csv"]

undirectedEdges = MapThread[UndirectedEdge, importedEdges // Transpose]

Graph[undirectedEdges, VertexLabels -> "Name"]

Mathematica is extremely versatile. If you can understand the format of the csv file, then you can reformat it as needed. Attached is a new notebook. I did not load csv file -- that's easy with Import. But for the array of 7 rows and 5 columns, I assume the format means that for each row, there is a directed edge from the first element to each of the remaining four. The data is therefor transformed by a rule which maps that structure to a list of 4 edge expressions, when applied to a row. When that rule is applied to the data, we get 7 lists of edges. They are flattened because Graph wants a single level list. If you could attach a perhaps abbreviated csv file and some words about its format I could be of more help.

Kind regards,

David
