Data Handling - choice of graphs by bhakti

I think that this type of graph is not appropriate as it does not specify the different number of countries with the same type of weather they are having.
 The other 3 graphs show the number of countries with the same weather.

  1. Pie chart shows the 'proportion', which tells us how often each type of weather occurs by the size of each pie. So, it's still appropriate.

    There are situations when we do not require the exact figures, but just need to tell the 'size' of occurrence at a glance. That's where pie chart is useful.

    So, which graph is inappropriate, and why?
