Data Handling: Choice of Graphs by Johanna Lim Ziyun


I think that out of the four ways to show information, the pie chart is not appropriate to represent the information. 
Firstly, the pie chart only has angles of the 5 types of weather and it is not really helpful as we are not able to tell how many countries are having this type of weather, we are only able to tell that Sunny (in this case) is the weather that most countries are having. 
Secondly, the pie chart does not show how many countries have the type of weather. 

The rest of the graphs are appropriate to showcase the information as the other graphs can relay the information clearly and it is vivid, not vague like the pie chart. The other graphs are able to show how many countries are having this weather and they are able to show the most common and least common weather among the countries more clearly.
