Ah, sorry. I repaste the code here - somewhat shortened:

<div role=img aria-labelledby=myImage aria-describedby=aLongDesc >
     <img id=myImage src=img.png
          alt="Chart showing Candidate X's 12% lead."  >

     Spreadsheet including full data set referenced in this chart.

Since you used the word "full data set", I guess the spreadsheet 
will not be a textual equivalent of the chart, but rather an 
augmented - full - version of the background material.

If so, then it does IMHO not fullfill the role of a @longdesc 
resource, since the @longdesc URI should merely have contained a 
textual variant of the Chart. (@longdesc = "long @alt".)
