There's kind of a tradition in my class at school. Every lunchtime, we all go out to buy some tea at one of the nearby teashops. Until recently, there were only two tea shops, Jill's Tea Shop and Tasty Tea. But at the end of April, I heard that a new tea shop called Tea 4 U would be opening at the beginning of May. I was curious—how would this new competition affect the other shops? And how would my classmates decide where to go for their tea? Would they stay loyal to their regular tea shop, or would they want to try something new? So, every lunchtime for the whole of May, I asked all of them where they had gotten their tea from, and I made this area graph to show the results.

我們班有個傳統，每到午餐時間，大家都會去附近的茶店買些茶飲。本來一直都只有「吉兒茶館」和「饗茶」兩間茶店，但到了四月底，我聽說五月初會新開一家「只有為你」茶館。我很好奇，新開張的競爭者會如何影響其他店家？還有，我的同學們會想去哪一家捧場？ 大家會忠於原味還是嚐鮮呢？ 所以，整整五月份的午餐時間，我都會詢問大家買了哪一家的茶飲，並將結果製成下表。
