This seems pretty cool, and being able to display charts easily is a valuable thing to have. There doesn't seem to be any fallback for people to view charts if they don't have the extension installed, however. Even just a link to something like the landing page, with the chart they're looking for in place of the US/Russia Nuclear stockpiles chart.
