         * of actually removing it from the array.
         * The empty position will be reused if a new graph is added.

         * \returns True if the graph was sucessfully removed (i.e it did exist in the #graphs array). False otherwise.

         * and nulling it in the array instead of removing the element completely in the #graphs array.
