+
+Check whether a graph is chordal.
+
+A graph is said to be *chordal* if every cycle of length `≥ 4` has a chord
+(i.e., an edge between two vertices not adjacent in the cycle).
+
+### Performance
+This algorithm is linear in the number of vertices and edges of the graph (i.e.,
+it runs in `O(nv(g) + ne(g))` time).
+
+### Implementation Notes
+`g` is chordal if and only if it admits a perfect elimination ordering—that is,
+an ordering of the vertices of `g` such that for every vertex `v`, the set of
+all neighbors of `v` that come later in the ordering forms a complete graph.
+This is precisely the condition checked by the maximum cardinality search
+algorithm [1], implemented herein.
+
+We take heavy inspiration here from the existing Python implementation in [2].
+
+Not implemented for directed graphs, graphs with self-loops, or graphs with
+parallel edges.
