You can write your own function in Javascript, much like the "words"
function that powers the tag cloud facet in this example:
http://people.csail.mit.edu/dfhuynh/projects/graph-based-exhibit/graph-based-exhibit2.html
The native functions are here

In your own code, instead of
<span ex:content=".Molecule_SMILES"></span>
you'd need
<span ex:content="showLines(.Molecule_SMILES)"></span>
and define showLines in the same way that "words" is defined in the
example above.
