Tools for nutritional value tracking and visualization I want to track the nutritional value of different flours over time. What I got so far is a
data table like this:

|------------|------------|------------|------------|
|   Flour    |   Date     |   Energy   |   Sugar    |
|------------|------------|------------|------------|
|   type 1   |   03/20    |   310      |   2        |
|   type 2   |   03/20    |   290      |   1.8      |
|   type 1   |   04/20    |   310      |   2.1      |
|   type 2   |   04/20    |   287      |   1.7      |


Over time, I will add more nutritional values for the flours already in the table and
might add more types of flour. I might also want to add additional columns e.g. for protein.
The nutritional values of the different flour types should then be plotted over time
like this:

Energy
|
|     *         *             * type 1
|     #                       # type 2
|               #
|
|-----------------------Date
    03/20     04/20


What are the best tools to implement such a project?
My constraints are that I only want to use free and open-source software which runs under Arch Linux and that that i can export the plots
I would recommend the Python libraries: matplotlib and seaborn for generating and exporting static plots, or Plotly for interactive plots with hover features that you can export to a web browser.
