Hi @nghenzi and others
The problem with the sunburst is that Panel does not automatically understand which panel type to put pyecharts objects in. If you replace the last line with pn.pane.ECharts(c, height=1000, width=1000).servable() it works. Please note it’s also important to set the height and width.
I’ve contributed a fix here https://github.com/holoviz/panel/pull/1877. Unfortunately it introduces “flickr” when making ECharts depend on sliders.
FYI. @nghenzi
