echo html only if the variable is not empty

I am trying to print the content of the variable and a <hr> tag after doing a check if the variable is not empty. The <hr> is getting echoed even if the variable is empty.

Here is what I have

<?php if (!empty($content['relationship_graph'])){ 
            print render($content['relationship_graph']);
            echo '<hr>';
          }
         ?>

Not very pro in PHP but looked at some documentation...Cant seem to figure out what I might be doing wrong

Here is what I ended up doing. It worked. 

if($content['relationship_graph']['#markup']['length'] != 0){
                  print render($content['relationship_graph']);
                  echo '<hr>';
              }

Value in it could be a blank space.

try..

<?php 
    if(!empty($content['relationship_graph']) && $content['relationship_graph']!=''){ 
        print render($content['relationship_graph']);
        echo '<hr>';
    }
?>
