Out of curiosity I’d love to see any examples where you think Plotly is especially strong for scientific plotting. I’ve used Plot lots and Plotly none, but I’d guess the big Plotly advantages right now are

- rich tooltips (coming soon in Plot)

- interactive pan & zoom

- multiple panels with shared scales? (like for marginal distributions; you can combine with HTML of course, but it’s not easy/built-in in Plot)
