OK. Not being fluent in French, and not knowing the vocabulary used in France, I can't evaluate these and find other sources. But, for one thing, however, the pie chart doesn't seem to include debt payments. Also, a proper comparison would include the regions.
Total: 676,625 millions (hover on the top bar, I can tell what the 366 bln in the headline refers to?).
Schools: 62,330 mln = 9.21%
Higher ed+research: 25,439 mln = 3.76%
Transport: 4,307 mln = 0.64%
Health: 1,379 mln = 0.2%
For a grand total of 13.81%. I'm not sure how you get to 1/4 going to education?
