Reading a Graph Object from a Text File

I'm reading through this blog post and the author appears to read this text document of contiguous US states and their neighbors as a graph object on which he then calls the function adjacency(S). I'm curious about how to do this myself, as the blog post defines

S = get_state_neighbors;

Without any reference to what get_state_neighbors is. I've tried downloading the text file and using

S=readcell("get_state_neighbors.txt");

however this produces a 53x1 cell array, which the adjacency function cannot be used on.

For each line of the text file, use addedge to add an edge between the first state whose abbreviation appears on the line and each of the others that appear on that line.

rawData = 'AL FL GA TN MS'

rawData = 'AL FL GA TN MS'

listOfStates = split(rawData)

listOfStates = 5×1 cell array
    {'AL'}
    {'FL'}
    {'GA'}
    {'TN'}
    {'MS'}

g = graph;
g = addedge(g, listOfStates(1), listOfStates(2:end))

g = 
  graph with properties:

    Edges: [4×1 table]
    Nodes: [5×1 table]

plot(g)

Thank you, I managed to generate my graph by reading the text file line-by-line and appending to the graph!
