If you really want to use LibreOffice - and it is a fine package with a lot of capability - it appears that you may be able to do what you need.
I opened your 'tabellendokument' in LO by double clicking and I get a spreadsheet with embedded graph showing temperature against month for a series of four years. If I select the graph (single click) and then right click on it, the drop down menu includes 'export as image'. Select it and one of the format options will be 'SVG - StarDraw 2.0'. Select it and hit 'save'. The resulting svg file opens in Inkscape and the text is editable as text and all other features appear to be editable too. (see attached)
What else do you need?
(Note this was accomplished using OS X 10.10, and LO 4.4.5.2 - things may differ on other platforms or versions)

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
I took one spreadsheet out of it: http://borumat.de/+svg/tabellendokument.ods
I exported it from Libreoffice as a PDF: http://borumat.de/+svg/tabellendokument.pdf
I imported the PDF into Inkscape: 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
