"World's Greatest Storytellers" Aren't Very Worldly

Raconteur produced an infographic with the title "World's Greatest Storytellers". Unfortunately, it's too Anglocentric. What about the great storytellers from Russia, France, Japan, and China?

The top 6 is a bit surprising. Roald Dahl and J.K. Rowling received more votes than Victor Hugo, Alexandre Dumas, Leo Tolstoy, Fyodor Dostoevsky, Gabriel García Márquez, Isaac Asimov, Ryūnosuke Akutagawa, and Lao She. A bit bold for it to be called "World's Greatest Storytellers", no?
