  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?
