It would appear that no one knows how to read a graph chart. Either that, or someone forgot how to create a graph chart. The data represented on the charts is in direct contradiction to the text of the article.
The numbers on the vertical DECREASE as they go up. That means that an upward graph line indicates a drop in site views, while a downward graph line indicates a RISE in site views. Not only that...but the entire chart is improperly labeled and identified. There is no mention of what the numbers on the right side represent. We are left to ASSUME they represent site traffic.
That seem to be the case.
