What are some examples of using Bokeh in Python?

Bokeh is a powerful library for creating interactive visualizations in Python. Here are a few examples:

1. Line plots for time series data.
2. Scatter plots for visualizing relationships between variables.
3. Heatmaps for displaying matrix data.
4. Bar charts for categorical data.
5. Interactive dashboards combining multiple plots.

Can you show me a simple line plot example?

Sure! Here's a simple example of a line plot using Bokeh:

from bokeh.plotting import figure, show
from bokeh.io import output_notebook

output_notebook()

x = [1, 2, 3, 4, 5]
y = [6, 7, 2, 4, 5]

p = figure(title='Simple Line Plot', x_axis_label='X-axis', y_axis_label='Y-axis')
p.line(x, y, legend_label='Line', line_width=2)

show(p)

This code will create a simple line plot with the specified x and y values.

How can I customize the plot's appearance?

You can customize the plot's appearance in several ways, such as changing colors, adding titles, and modifying axes. For example:

p.title.text = 'Customized Line Plot'
p.line(x, y, line_color='green', line_width=3, legend_label='Custom Line')
p.xaxis.axis_label = 'Custom X-axis'
p.yaxis.axis_label = 'Custom Y-axis'

This will change the line color to green and update the axis labels.
