Now is an era of information explosion. Information visualization uses visual processing of information in graphics and images to help people quickly understand and analyze data. (This plan is a normal operation plan)

All the pictures are matched with the visual processing displayed on the mobile phone and the theme. The more color the outer circle, the more brightly the line points to the major that represents the most used major for this application.
(Outest circle color brightest = maximum usage)

Men and women are represented by blue and red respectively, which is intuitive and concise.

Of course, being a designer definitely needs some diversified data expression elements.

The vivid player image can also set off the theme.

Finally, my five-star APP recommendation.
