Display Google Map shortcode, not the map itself

Hi
I have a small problem. I want to show how to use google map shortcode to insert a map in a post, but the shortcode (with empty adress) shows the world map. I want the shortcode to be visible, not the map.

The shortcode is the following:
[su_gmap width="350" height="250" responsive="no" address=""]

I used the “code” brackets but no success. Any idea?

Thanks in advance
