LFC Goal Machine
The LFC Goal Machine web app at lfcgm.lfcsorted.com plots a player's age against the league goals that the player scored in a top level season. For more information see the About tab in the app.
Give it a go! If you like the app please tweet @lfcsorted.
I've also created an R version of the app, with an enhanced user interface, at https://terrydolan.shinyapps.io/lfcgmR.
