Sample

Try ipyvizzu in JupyterLite with the following sample.

# import pandas, js, asyncio, StringIO and ipyvizzu

import pandas as pd

# chart = Chart(width="640px", height="360px", display=DisplayTarget.END)
# chart = Chart(width="640px", height="360px", display=DisplayTarget.MANUAL)


# add data to Chart
# download data from
# "https://ipyvizzu.vizzuhq.com/0.17/showcases/titanic/titanic.csv"

        }
    )
)

# add style to Chart

chart.animate(Style({"title": {"fontSize": 35}}))


# display Chart with show or _repr_html_ method (display=DisplayTarget.MANUAL)

# chart.show()
