We have been using Apache ECharts in our products[1] since 2020.

Cannot recommend it enough - absolutely fantastic library, great documentation, zero issues of any impact to us in five years.

My only wish is for the keyboard accessibility ticket[2] to get some love!

Funny to see you here. I’m from operata.io (also a Melbourne based startup) and would see your website (operatr.io) when I would mis-spell mine!
