That is not an answer.
1. did the website in question faithfully reproduce the numerical data in question?
2. was the numerical data faithfully rendered into graphic form without alteration?
If the answer to (1) and (2) are 'yes', then, it doesn't make one damned bit of difference who created or posted the graphs, does it?
Numbers are numbers, and they speak for themselves.
Logic drives the conclusion that one draws from such numbers.
If you are able to challenge al-Jazeera's numbers, or the faithful reproduction of those numbers, or their rendering into graphic form, then, by all means, present your case.
