We're trialing ECharts on a couple dashboards at the moment and it's improved velocity a lot over previous D3-based approaches. This has been my experience in other companies too, where a purist developer will come along and start building yet another custom D3 solution which takes so long to deliver that the users just build a pipeline to dump the data and hack their own charts together in a different tool instead.

My feeling is that D3 just isn't worth it unless you are building a bespoke visualization for a unique dataset. For most everything else, ECharts is so much faster to deliver value to the users. The ease-of-use of ECharts reminds me of Highcharts back in the day, except it's free! I'm not sure it has a very strong support network behind it, but perhaps that will improve as more popular tools switch (Gitlab, Superset etc).
