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.
</a></div>
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".)
