`graph.neighborhood()`

was renamed to `make_ego_graph()`

to create a more
consistent API.

## Arguments

- graph
The input graph.

- order
Integer giving the order of the neighborhood.

- nodes
The vertices for which the calculation is performed.

- mode
Character constant, it specifies how to use the direction of the edges if a directed graph is analyzed. For ‘out’ only the outgoing edges are followed, so all vertices reachable from the source vertex in at most

`order`

steps are counted. For ‘"in"’ all vertices from which the source vertex is reachable in at most`order`

steps are counted. ‘"all"’ ignores the direction of the edges. This argument is ignored for undirected graphs.- mindist
The minimum distance to include the vertex in the result.
