How do I create a scatter plot using Plotly in Python?

You can create a scatter plot in Plotly using the plotly.express module. Here's a simple example:

import plotly.express as px
import pandas as pd

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

# Create scatter plot
fig = px.scatter(df, x='x', y='y', title='Simple Scatter Plot')
fig.show()

What if I want to customize the markers in the scatter plot?

You can customize the markers by using the update_traces method. For example:

fig.update_traces(marker=dict(size=12, color='red', symbol='circle'))

Can I add a trend line to the scatter plot?

Yes, you can add a trend line using the trendline parameter in px.scatter. Here's how:

fig = px.scatter(df, x='x', y='y', trendline='ols')

How do I save the scatter plot as an image?

You can save the plot as an image using the write_image method. Make sure to install the kaleido package:

fig.write_image('scatter_plot.png')
