How can I create interactive plots using Plotly Express?

You can create interactive plots using Plotly Express by importing the library and using functions like px.scatter() or px.line(). What type of plot are you interested in?

I'm interested in creating a scatter plot with some sample data.

Great! You can use the following code:

import plotly.express as px
import pandas as pd

data = pd.DataFrame({
    'x': [1, 2, 3, 4, 5],
    'y': [10, 11, 12, 13, 14]
})

fig = px.scatter(data, x='x', y='y', title='Sample Scatter Plot')
fig.show()

This will create a simple scatter plot.

Can I customize the markers in the scatter plot?

Yes, you can customize markers by adding parameters like size, color, and symbol. For example:

fig = px.scatter(data, x='x', y='y', size='y', color='y', symbol='y', title='Customized Scatter Plot')

This will vary the size and color of the markers based on the 'y' values.

What if I want to add a trend line to my scatter plot?

You can add a trend line by using the trendline parameter in the px.scatter() function. For example:

fig = px.scatter(data, x='x', y='y', trendline='ols', title='Scatter Plot with Trend Line')

This will fit an ordinary least squares regression line to your data.
