I've been using apache echarts for a while. It is excellent. As you dig deep, some of the examples and libraries are in Chinese, which can be challenging.
The only real drawback that I've discovered is that it uses canvas to generate the charts. So, when you UI changes to dark mode, you need to reload your charts to update the color scheme ... which in the grand scheme of things is really minor.
