Exactly. The point of the graph is that although more people live in these countries (= area under the curve), the proportion and - more importantly - the abolute number of people in deep poverty (< 1 $ a day, corrected for inflation) has fallen. The original, properly annotated, is here. The heading means "the rich get richer, but so do the poor".
My image hosting service (Photobucket) won't allow me to hotlink to here, unless I pay US$399 per year, which is about US$397 more than I'm willing to pay.
What alternatives, so that I may post the next graph?
You can insert any online image with the 'insert image' button. Or you can attach any image from your computer with the 'upload attachment' function. Would one of those options work for you?
