Use shinyCircos online

shinyCircos is deployed at https://yimingyu.shinyapps.io/shinycircos/ and http://shinycircos.ncpgr.cn/ for online use.
shinyCircos is idle until you activate it by accessing the two URLs.
So it may take some time when you access this URL for the first time.
Once it was activated, shinyCircos could be used smoothly and easily.
