We use highcharts to power most of our charting (we're an embedded analytics platform) and switched over from from chart.js

It's fairly powerful but also looks more polished out of the box. Some limitations on styling but that depends on your application/use case.

Highcharts is like "ol' reliable" when it comes to chart libraries, I first used it over ten years ago for a customer-facing investment banking webapp and as far as I know it's still around.

Charting libraries are hard, Highcharts got a lot of things right back then and I don't think it's stopped since then.

I am also a big fan of Highcharts. It is not cheap though, especially for projects that aren't making any money yet

Highcharts is nice. My only complaint is that the type declarations are absolutely huge--like 300k lines. It makes my IDE grind to a halt when using TypeScript. However, the typescript compiler is unfazed by it.

Highcharts is what some big financial clients I know use. It seems pretty solid and easy to learn and integrate from my experience with it.
