A graph data structure library for Elm, inspired by Haskell Data.Graph. This package implements a finite, directed graph type using an adjacency list representation, where vertices are identified by integers. It also includes an SCC (Strongly Connected Component) type for managing and analyzing strongly-connected components within the graph.

To install the package, run the following:

elm install guida-lang/graph

Here’s an example of how to use the Data.Graph in Elm:

import Data.Graph as Graph exposing (Graph)

graphWith3Vertices : Graph
graphWith3Vertices =
    let
        ( graph, nodeFromVertex, vertexFromKey ) =
            Graph.graphFromEdges [ ( "a", 'a', [ 'b' ] ), ( "b", 'b', [ 'c' ] ), ( "c", 'c', [] ) ]
    in
    graph
