How can I add interactivity to my Plotly graphs in Python?

You can add interactivity to your Plotly graphs by using features like hover text, clickable legends, and dropdown menus. Would you like a code example?

Yes, please provide a code example for a scatter plot with hover text.

Here's a simple example:

import plotly.express as px

# Sample data
df = px.data.iris()

# Create scatter plot
fig = px.scatter(df, x='sepal_width', y='sepal_length', color='species',
                 hover_data=['petal_length', 'petal_width'])

# Show the plot
fig.show()

This will display a scatter plot where hovering over points shows additional information.

That looks great! Can I also add a dropdown to filter the species?

Absolutely! You can use the update_layout method to add a dropdown. Here's how:

fig.update_layout(
    updatemenus=[{
        'buttons': [
            {'label': 'All', 'method': 'update', 'args': [{'visible': [True, True, True]}]},
            {'label': 'Setosa', 'method': 'update', 'args': [{'visible': [True, False, False]}]},
            {'label': 'Versicolor', 'method': 'update', 'args': [{'visible': [False, True, False]}]},
            {'label': 'Virginica', 'method': 'update', 'args': [{'visible': [False, False, True]}]},
        ],
        'direction': 'down',
    }]
)

This will allow you to filter the species displayed in the plot.
