No, if we can condense something in a few short statements, we don't generally bother making a graph. We exactly make graphs when something is not easily explained in words, but instead requires visualization.

Of course, not all graphs are equally information dense, and some are only used for decorative purposes more than actually conveying information. But in the general case, and especially when used well, graphs convey much more information at a glance than a short text description could.
