Data Handling: Choice of Graphs by Bryan Lee

In my opinion, I feel that the line graph is wrong because it is not a decrease in the number of countries with windy weathers but instead, it should be 11 countries with sunny weather and 0 countries with windy weather.

Pie charts: The pie chart shows that all countries have sunny weather.
Pictogram: The pictogram shows correctly the number of countries with sunny weather.
Bar Graph: The bar graph indicates that all 11 countries have sunny weather and the height of each bar is according to the number of pictures of the weather on the diagram.
