Feature request: Sparse adjacency matrix graph creation

Feature request: Sparse adjacency matrix graph creation: a task in LegoFlow-SWE (Harbor dataset). We need the ability to create graphs directly from sparse adjacency matrices ( igraph sparsemat t ), without having to convert to dense format first. Currently, igraph adjacency() and igraph weighted…

The task

We need the ability to create graphs directly from sparse adjacency matrices (`igraph_sparsemat_t`), without having to convert to dense format first. Currently, `igraph_adjacency()` and `igraph_weighted_adjacency()` only accept dense matrices (`igraph_matrix_t`). For large, sparse graphs, converting to dense is…
