I replaced ChartJS with Victory on a recent project for charting investment performance, and was generally very pleased with the experience.

The focus on composable components fits well with the React way of working, and enables easy customisation (which was one of the main reasons for moving away from ChartJS) - you can even directly add SVG elements inside your Victory chart components if you want custom graphical elements.

Another interesting result of the switch was that the rendering quality of the vector (SVG) charts rendered by Victory was a lot nicer than the raster (Canvas) ones rendered by ChartJS, and it particularly fared much better at rendering smooth interpolation curves for a chart with a fairly large amount of data which looked "bumpy" with ChartJS.

Overall I'd highly recommend giving Victory a go if you need charts which aren't too specialised but do require some customisation. It seems like some of the paid-for solutions such as Highcharts are probably still the best option if you require something more niche.
