A couple notes:

• As a first milestone, this currently only applicable to the the rating history charts on user profile pages.
• For now, I couldn’t figure out how to make it change color schemes dynamically (light vs. dark), so it requires a reload to apply the theme changes.
• It still isn’t localized properly (though it seems Plotly.js does support localization).
• It allows scrolling past the available date range, which can look a bit confusing (I’m not sure Plotly.js has inbuilt functionality to prevent that).
• The control at the bottom is absent, and so are the intervals buttons at the top.
