I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">marine map</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for chart that I've seen before include "Table or diagram" , "Nautical map" , "[LOVE ME DO] became the first of many to ..." , "Marine map" , "series of plots?" .)
