在bokeh中创建侧面板，用于显示悬停数据点的详细信息

from bokeh.plotting import figure, show
from bokeh.models import HoverTool, ColumnDataSource

p = figure(plot_width=400, plot_height=400)
points = p.circle(x=[1, 2, 3, 4, 5], y=[6, 7, 2, 4, 5], size=10)

source = ColumnDataSource(data={
    'x': [1, 2, 3, 4, 5],
    'y': [6, 7, 2, 4, 5],
    'info': ['Info 1', 'Info 2', 'Info 3', 'Info 4', 'Info 5']
})

hover_tool = HoverTool(renderers=[points], tooltips=[('Info', '@info')])
p.add_tools(hover_tool)

show(p)
