Using pyecharts?

PyEcharts is a comprehensive interactive chart library built on Echarts which is open source and perfect for Shiny interactivity (I use R package echarts4r which wraps Echarts for R Shiny).

I've tried using it with Shiny for python with no success as a plot, ui and ipywidget. Below is one attempt which isn't working.

from shiny import App, render, ui
from pyecharts.charts import Bar
from pyecharts import options as opts
from shinywidgets import output_widget, render_widget

app_ui = ui.page_fluid(
    ui.layout_sidebar(
        ui.panel_sidebar(
        ), 
        ui.panel_main(            
            ui.output_ui("echart_test"),  #guessing here
        )
    )
)


def server(input, output, session):

    @output
    @render.ui
    def echart_test():
        bar = (
            Bar()
            .add_xaxis(["衬衫", "毛衣", "领带", "裤子", "风衣", "高跟鞋", "袜子"])
            .add_yaxis("商家A", [114, 55, 27, 101, 125, 27, 105])
            .add_yaxis("商家B", [57, 134, 137, 129, 145, 60, 49])
            .set_global_opts(title_opts=opts.TitleOpts(title="某商场销售情况"))
        )
        return bar.render() #guessing here too

app = App(app_ui, server)

Start with the provided App, output, render.ui, shinywidgets, and render_widget reproducer, then compare its pyecharts usage with the linked pyecharts documentation. No repository file or test is named; done would require a defined, working integration path or a documented limitation for pyecharts with Shiny for Python.
