Charting on the web

I've been collecting cool visualisation libraries over the years. Much of those which I thought looked interesting 6-8 years ago are long gone already. One of the few that did survive was a commercial one, Highcharts, which is still worth checking out, even today. As for the open source ones, I have considered often alternatives to Chart.js, but as this project is still seeing active development after > 10 years I think Chart.js the safest bet you can make when considering 2D graphing libraries.
