@m-aciek WDYT?

It looks like on the chart the progress is like 14% now?

I agree, I will look into it. My data, generated using potodo, shows 13.49 as the highest entry. I assume it is therefore a side effect of the rendering. Though the data is also higher than that of the Transifex statistics, which is odd.

Also it would be nice to publish/link to the generating script to allow for updates in future and/or automation.

I will add a comment to a gh gist with it to the README once I sort out your other comments.

Images updated. Note that the line count difference between the files is because Inkscape seems to compress them, whereas the raw Matplotlib svg is spread out. I doubt it makes a difference.

It does still look at bit like it's at 14%, but from matplotlibs interactive viewer it confirms it's ~13.5 (which is still a minor mystery, but the chart in general was not designed with accuracy in mind).

I simplified the messages, though I kept the initial date.

If this is good to go I'll upload the scripts as gists (and link them) and merge.

the blurb package should be installed in the environment.

I used my system environment, which does have blurb, maybe it is because I used make gettext rather than the builder directly.
