本项目是受github-contributions-chart启发并使用其提供的数据接口，使用R & Shiny编写。
Inspired by daattali/shiny-server, I decided to build my own shiny server. Finally, I made it! Now you can access it by https://czxa.top/shiny/. Since I haven’t get this server recorded (In China, all websites should be recorded at MIIT, a.k.a, Ministry of industry and information technology of China). After I get it recorded, you can access it by domain name, as is https://czxa.top, but this domain name now is point to my blog deployed at GitHub.
