Three-panel diagram showing how livelink works. Panel 1, "You write R": a code block wrapping a short script in webr_repl_link(), where the script loads the mtcars dataset and plots mpg against weight with steelblue points. A caption notes that a string, a file path, or the clipboard work too. Panel 2, "You get a URL": a long webr.r-wasm.org link with the code encoded in the fragment. Panel 3, "They get a live R session": a browser window with four panes, an editor holding script.R, a file browser showing home/web_user/script.R, a terminal where source('script.R') and mean(mtcars$mpg) return 20.09062, and a pane displaying the resulting scatter plot.
