Having frequent need to create publication grade graphs from raw data I find the most reliable workflow to be :
Plot the data using gnuplot or gnu octave (or more recently Veusz - an excellent addition to the FOSS library) These programs can all accept a variety of input files - .csv, ascii etc and export to a broad spectrum of graphic formats including of course .svg. R also has amazing graphics capabilities but may involve a longer, steeper learning curve.
I then typically import the svg to Inkscape to pretty it up. It must be said though, that Veusz eliminates the need for much of what formerly was done in this step.
There are are horses for courses ........ Pick the best one for your needs. It's unlikely to involve LibreOffice or Excel.

Of course the goal "high quality SVG" is not an abstract one.
Only good code allows to manipulate the parameters of the SVG effectively, when you want to change the appearance.
Sorry, when I'm sceptical about the suggested way.
You may be right about the considered option compared to other's suggestions. But the output for pdf will not be rather, it'll be vector and you'll get a good visual which looks like the visuals found in office.
I tried it.
Source of a simple spreadsheet with a chart: http://www.ooowiki.de/DiagrammMitLinien.html http://www.ooowiki.de/DiagrammMitLinien.html
I took one spreadsheet out of it: http://borumat.de/+svg/tabellendokument.ods http://borumat.de/+svg/tabellendokument.ods
I exported it from Libreoffice as a PDF: http://borumat.de/+svg/tabellendokument.pdf http://borumat.de/+svg/tabellendokument.pdf
I imported the PDF into Inkscape: http://borumat.de/+svg/tabellendokument.svg http://borumat.de/+svg/tabellendokument.svg
The SVG code of the chart is not editable/usable, because it uses only "svg:path". And it is full of redundances.
I'm not a programmer, but I think that only a specialized software/plugin can create high quality (editable) SVG code from spreadsheet data.
All the concepts of charts has to be "mapped":
axis, grid, scale, legend, ...
Semantically useful IDs has to be used and so on ...
Best, Andreas
