Wait until Plotly is ready. px and go are preloaded. Always fig.show().

Goal

Run every block and confirm the chart is visible.

df = pd.DataFrame({
    "city": ["Nairobi", "Mombasa", "Kisumu", "Nakuru", "Eldoret"],
    "units": [21, 15, 15, 18, 12],
    "shillings": [2100, 1500, 1480, 1750, 1190],
})
fig = px.bar(df, x="city", y="units", title="Units")
fig.show()
print("bar")

df = pd.DataFrame({
    "month": ["Jan", "Feb", "Mar", "Apr"] * 2,
    "mm": [48, 55, 92, 150, 22, 18, 40, 80],
    "city": ["Nairobi"] * 4 + ["Mombasa"] * 4,
})
fig = px.line(df, x="month", y="mm", color="city", markers=True, title="Rain")
fig.show()
print("line")

Pitfall

Without fig.show() the Plot pane stays empty.
