This type of "translating" from one format to another is often called "metadata mapping" or "field mapping," and is related to "data mapping", and "semantic mapping".

Save this script as e.g. lineplot.py and then run it with python lineplot.py. After a few seconds, a window with the interactive graphical output should pop up, and the SVG will also be in the folder. Numerous examples with Python source code are available, for example the Matplotlib gallery and commons:Category:Valid SVG created with ...
