If these are fuel costs that you want to use to minimize expenses given that each of the industries / applications on the left side require a certain amount of fuel and given other constraints, I'm not sure that a network graph is the best tool for this application. I'd read this into a matrix or a table (the latter using readtable) and then use some of the functions from Optimization Toolbox to perform that optimization.
If you really need or want to create a graph or digraph from this data, you're going to need to make a square adjacency matrix. Use readtable as I mentioned above or the tools listed on this documentation page for the type of file in which this data is stored to read it into a matrix or table, make a square matrix (probably by padding with zeros), then build and analyze your graph or digraph.
