- * The data structure is a proximity graph, containing edges when the edge length is less or equal
- * to a given max_radius. Edge length is computed from `Gudhi::cech_complex::Sphere_circumradius` distance function.
+ * Cech complex is a simplicial complex constructed from a proximity graph, where the set of all simplices is filtered
+ * by the radius of their minimal enclosing ball and bounded by the given max_radius.

  * \tparam SimplicialComplexForCechComplex furnishes `Vertex_handle` and `Filtration_value` type definition required
