Assignment 4: Yi Zhang

I’m interested in the development of smartphone brands. I got data about worldwide smartphone brands market share in 2015 and 2016 and made two pie charts. From these two charts, we can see that Samsung and Apple are still the two biggest players in the market, but their market shares slightly decrease from 2015 to 2016. The Chinese brands Huawei, Oppo, and BBK grew quickly in 2016.
