A (strongly) Helly graph is a connected graph for which any finite (resp. finite or infinite) family of pairwise non-disjoint balls has a non-empty intersection. Many interesting properties of (strongly) Helly graphs are known, such as results concerning geodesic convexity, fixed point properties, etc. This article is a survey of such a type of results.
