Shouldn't this be an extension? Since we have the visualization libraries
GraphMakieandMakieas an extension too.There was a problem hiding this comment.

I see your point but in this case no. The reason is that package extensions are there to avoid precompile and load time overheads.
In this case, ECharts is a JavaScript library (so only gets loaded on the web browser/notebook/VSCode, it doesn't get loaded to the Julia session). Furthermore, JLL packages don't load anything to memory... they are just wrappers over some "binary" files stored on disk. And the minified file just weights 1MiB...
