    Converts CSS styles into inline style attributes in your HTML code

    ...This utility was developed as part of Intervals to deal with the problems posed by certain email clients (namely Outlook 2007 and GoogleMail) when it comes to the way they handle styling contained in HTML emails.

While attempts are being made to develop common email standards, implementation is still a ways off. The primary problem with uncooperative email clients is that most tend to only regard inline CSS, discarding all style elements and links to stylesheets in link elements. ...

Odds are good your React app already has an opinion on how animation, theming, or styling is done. visx is careful not to add another one and integrates with all of them. As you start using visualization primitives, you’ll end up building your own charting library that’s optimized for your use case. You’re in control. And most importantly, it’s just React. If you know React, you can make visualizations. It’s all the same standard APIs and familiar patterns. visx should feel at home in any React codebase.
