如何使用全息视图和Bokeh在Sankey图中显示HoverTool中的数据集标签

from bokeh.plotting import figure, show, output_file
from bokeh.models import HoverTool, Sankey

# 假设我们有以下数据
nodes = {
    'nodes': [
        {'name': 'Node A'},
        {'name': 'Node B'},
        {'name': 'Node C'}
    ]
}

links = {
    'links': [
        {'source': 0, 'target': 1, 'value': 20},
        {'source': 1, 'target': 2, 'value': 30},
        {'source': 0, 'target': 2, 'value': 10}
    ]
}

# 创建Sankey图
p = figure(title="Sankey Diagram with HoverTool", tools="")
sankey = Sankey()
sankey.add(nodes=nodes['nodes'], links=links['links'], color=['blue', 'red', 'green'])

# 添加HoverTool
hover = HoverTool(tooltips=[
    ("Source", "@source_name"),
    ("Target", "@target_name"),
    ("Value", "@value")
])
p.add_tools(hover)

# 将Sankey图添加到图表中
p.renderers.append(sankey)

# 输出结果
output_file("sankey_bokeh.html")
show(p)
