I made a R web-app in Shiny which does curve fitting of a Four Parameter Log Logistic function (which is the S-curve discussed in the article) against the John Hopkins data:
"Sweden FHM" is the default country, which is a different data source, it's using data from the Folkhälsomyndigheten FHM (Swedish Public Health Agency), which is adjusted by death date and not reporting date as the John Hopkins data is.
