What do y'all recommend for frequently updating charts i.e. streaming data sources with histograms, etc?

Highcharts would be my goto for live data charts that updated continuously. The framework is free to use for non-commercial or personal projects via a CC license: https://www.highcharts.com/docs/working-with-data/live-data

It's a popular framework, so a lot of my questions were answered on Stack Overflow.
