I think maybe having a pie chart or something to visually display the weekly hardware sales could be nice (maybe with the ability to toggle between each regions sales).
But anything more might be going a bit overboard. The space on the front page is quite limited as it is trying to fit in sales figures, news/articles and the forums all at once. I think a bunch of randoms charts and graphs being squished in would make things look too cluttered.
The charts which already get created and posted in the news/articles section is a good enough imo. Plus having them there allows people to post comments on them too.
