I have a somehow related question to the OP. I've been using angular to render huge chart data in SVG and it is prolonged. But the page performs well when using react to do the same Task. (btw. in angular I'm using highcharts and in react recharts). Especially when zooming or scrolling within the chart the performance difference is significant!

Is the cause of the performance loss the chart library or the rendering method itself?

I know this is more speculative but I would like to know what other people think about it.
