On taxes and growth

Tired of hearing the mantra about how good are tax cuts for the economy and people, I decided to try to find for myself with the available data if this was true or not. So, I decided to create a Gapminder graph to check possible correlations between Growth, Unemployment and the top marginal tax rate.

I cannot find definite trends, but it seems pretty obvious that high taxes do not kill the economy, neither tax cuts prevent unemployment.
