The bundle a knitted document carries for its charts

The widget, and a knitted document in the HTML output that cannot show its charts inline (see knitr_chart_output()), put each chart in a srcdoc iframe whose <script> loads maidr.js from the CDN. That document lives in an attribute, where neither pandoc's --embed-resources (R Markdown's self_contained, Quarto's embed-resources) nor anything else that rewrites a page's resources can see it, so a self-contained document still needed the network to make its charts accessible, and offline they were plain pictures.

Usage

maidr_page_bundle_dependency()

Value

A single htmltools::htmlDependency()

Details

This dependency gives the document one copy of the bundle that the tooling does see: linked from the _files folder, or embedded into the page when the document is self-contained. Its scripts are of a type no browser runs, so the page itself is left alone; a chart frame whose CDN load fails reads the copy from its parent instead (see maidr_cdn_loader_script()).
