This is a generic function for creating graphs.

## Details

`make_()`

is a generic function for creating graphs.
For every graph constructor in igraph that has a `make_`

prefix,
there is a corresponding function without the prefix: e.g.
for `make_ring()`

there is also `ring()`

, etc.

The same is true for the random graph samplers, i.e. for each
constructor with a `sample_`

prefix, there is a corresponding
function without that prefix.

These shorter forms can be used together with `make_()`

.
The advantage of this form is that the user can specify constructor
modifiers which work with all constructors. E.g. the
`with_vertex_()`

modifier adds vertex attributes
to the newly created graphs.

See the examples and the various constructor modifiers below.

## Examples

```
r <- make_(ring(10))
l <- make_(lattice(c(3, 3, 3)))
r2 <- make_(ring(10), with_vertex_(color = "red", name = LETTERS[1:10]))
l2 <- make_(lattice(c(3, 3, 3)), with_edge_(weight = 2))
ran <- sample_(degseq(c(3, 3, 3, 3, 3, 3), method = "simple"), simplified())
degree(ran)
#> [1] 3 3 3 1 3 3
is_simple(ran)
#> [1] TRUE
```
