# Output of plantri and graphs.planar_graphs

I find the documentation of Sage much lacking what is the output of `plantri`

and `graphs.planar_graphs`

?

I assumed the output would be graphs (could not find documentation on this) and did the following

```
l = graphs.planar_graphs(4, dual=False)
gen = list(l)
ii = 1
G = gen[ii]
p = G.plot()
p.show()
```
