Wow, I just tried it out. This is really great. And it solves my interactive plot saving requirement. Easy as doing `Plotly.savehtml(fig, "test_fig.html")` :). Thanks!

Could you elaborate? I see that Plotly.js is a JavaScript library, but is there special integration with VSCode?

yes, it integrates with the VSCode plotting pane. Not exactly sure where this happens, though.
