What are some examples of using Plotly for data visualization?

Plotly is a powerful library for creating interactive graphs. For example, you can create line charts, scatter plots, and 3D surface plots.

Can you show me how to create a scatter plot with Plotly?

Sure! You can create a scatter plot using the following code:

import plotly.express as px
import pandas as pd

data = pd.DataFrame({'x': [1, 2, 3, 4], 'y': [10, 11, 12, 13]})
fig = px.scatter(data, x='x', y='y', title='Scatter Plot Example')
fig.show()

What about creating a 3D surface plot?

To create a 3D surface plot, you can use this code:

import plotly.graph_objects as go
import numpy as np

x = np.linspace(-5, 5, 100)
y = np.linspace(-5, 5, 100)
X, Y = np.meshgrid(x, y)
Z = np.sin(np.sqrt(X**2 + Y**2))

fig = go.Figure(data=[go.Surface(z=Z, x=X, y=Y)])
fig.update_layout(title='3D Surface Plot Example')
fig.show()

Can I customize the colors in my plots?

Absolutely! You can customize colors using the color_discrete_sequence parameter in Plotly Express or by setting the colorscale in Plotly Graph Objects.
