That second graph is horrendously misleading. It does a pretty bad job of comparing the numbers between browsers.
They only just stopped using a translucent 3D pie-chart. But it's still tilted, drop-shadowed, single colored and, most importantly of all, a friggin pie chart in which we need to eyeball differences between several items less than 5%.
Just give us a table of figures and a bar chart for love of tufte. If you want to be trendy make it sortable with javascript.
And it's the trends that actually count anyway! I truly dispair every month when they wheel this out.
For graph 2, the lie factor for each bar graph is:
IE: .25 / .62 = .403
FF: .25 / .2383 = 1.04
Safari: .25 / .0417 = ~6
Chrome: .25 / .034 = 7.35
