Yeah the charts can be quite easily critiqued (what charts don't?). Would be great to see for example a clearer definition of the dollars spent.

But you also need to remember that the statement here is a comparative one. Higher ampunt od publications is a fact and npt unreasonable to then deduce that more research is done in china than in USA.

Now that I think about this, its just a terrible article: Graphs should never be posted Without a grounded analysis.
