如何使用Plot.ly将“播放”按钮合并到Dash by python仪表板中？

pip install plotly
pip install dash

import dash
import dash_core_components as dcc
import dash_html_components as html
import plotly.graph_objs as go

app = dash.Dash(__name__)

fig = go.Figure(
    data=[go.Scatter(x=[1, 2, 3], y=[1, 3, 2])],
    layout=go.Layout(
        updatemenus=[
            dict(
                type="buttons",
                buttons=[
                    dict(label="播放", method="animate", args=[None, {"frame": {"duration": 500, "redraw": True}}]),
                    dict(label="暂停", method="animate", args=[[None], {"frame": {"duration": 0, "redraw": False}, "mode": "immediate"}])
                ],
            )
        ]
    )
)

app.layout = html.Div(children=[
    dcc.Graph(id='graph', figure=fig)
])

if __name__ == '__main__':
    app.run_server(debug=True)
