I have a social network graph that I have made in Matlab using the graph object:

```
G = graph(weight);
LWidths = 10*G.Edges.Weight/max(G.Edges.Weight);
h = plot(G,'NodeLabel',cellstr(screen_names),'LineWidth',LWidths);
for i = 1:nnodes
highlight(h,i, 'MarkerSize', counts(i))
end
```

where `weight`

is an adjacency matrix, and `counts`

is a vector with the node sizes. It looks something like this:

Now, I'm not happy with how this looks, so I want to make it with Tikz instead. So my question is: is it possible to produce this type of graph with Tikz from an adjacency matrix where the edges are of different width taken to be the nonzero elements of the matrix. The size of the nodes should also be different. I'm not very experienced in Tikz, so any guidance in how to proceed would be highly appreciated.

I have read this similar post, but I'm still not sure how to handle different edge widths and node sizes. Also, is it required to explicitly give the coordinates for the nodes or can they be automatically generated, as in Matlab?

Here is the `weight`

matrix:

```
weight =
0 741 630 406 325 325 351 0 300 276
741 0 406 351 276 0 0 0 0 0
630 406 0 300 0 276 300 0 0 0
406 351 300 0 0 0 0 0 0 0
325 276 0 0 0 0 0 0 0 0
325 0 276 0 0 0 276 0 0 0
351 0 300 0 0 276 0 0 0 0
0 0 0 0 0 0 0 0 0 0
300 0 0 0 0 0 0 0 0 0
276 0 0 0 0 0 0 0 0 0
```

and `counts`

vector:

```
counts =
56 42 39 34 32 31 30 29 28 28
```

A bit crude, but sort of works OK and requires

`lualatex`

. A simple parser (which just matches on non-whitespace) plus a graph drawing macro.
