You need to adjust the size of the output picture; you can do this with the `figsize`

keyword:

```
sage: n = 5
sage: node = {}
sage: node[''] = [str(x) for x in range(n)]
sage: for x in range(n):
... node[str(x)] = [str(x) + str(y) for y in range(n)]
...
sage: g = Graph(node)
sage: P = g.plot(layout='tree', tree_root='')
sage: P.show(figsize=[10,10])
```

For larger graphs, you'll probably need to use an even larger `figsize`

, determined by the number of leaves on the bottom row.
