While the supercomputers themselves are interesting, I really like graphic. I think it displays the information in a more clear and compelling way compared to something like a stacked column chart, like <a href="http://www.highcharts.com/demo/?example=column-stacked&theme=default" rel="nofollow">http://www.highcharts.com/demo/?example=column-stacked&t...</a>, which would just be too busy with a lot of information.
