高级python数据可视化关系图代码

以下是使用 Plotly 绘制高级关系图的 Python 代码示例：

import plotly.graph_objs as go
import networkx as nx

# 创建一个复杂的关系图
G = nx.random_geometric_graph(200, 0.125)
pos = nx.get_node_attributes(G, 'pos')

# 设置节点和边的样式
edge_trace = go.Scatter(
    x=[],
    y=[],
    line=dict(width=0.5, color='#888'),
    hoverinfo='none',
    mode='lines')

for edge in G.edges():
    x0, y0 = pos[edge[0]]
    x1, y1 = pos[edge[1]]
    edge_trace['x'] += [x0, x1, None]
    edge_trace['y'] += [y0, y1, None]

node_trace = go.Scatter(
    x=[],
    y=[],
    text=[],
    mode='markers',
    hoverinfo='text',
    marker=dict(
        showscale=True,
        colorscale='YlGnBu',
        reversescale=True,
        color=[],
        size=10,
        colorbar=dict(
            thickness=15,
            title='Node Connections',
            xanchor='left',
            titleside='right'),
        line=dict(width=2)))

for node in G.nodes():
    x, y = pos[node]
    node_trace['x'].append(x)
    node_trace['y'].append(y)

# 设置节点的颜色和大小
for node, adjacencies in enumerate(G.adjacency()):
    node_trace['marker']['color'].append(len(adjacencies[1]))
    node_info = '# of connections: ' + str(len(adjacencies[1]))
    node_trace['text'].append(node_info)

# 绘制关系图
fig = go.Figure(data=[edge_trace, node_trace],
                layout=go.Layout(
                    title='<br>Network graph made with Python',
                    titlefont=dict(size=16),
                    showlegend=False,
                    hovermode='closest',
                    margin=dict(b=20, l=5, r=5, t=40),
                    annotations=[dict(
                        text="Python code: <a href='https://plotly.com/python/'>plotly.com/python</a>",
                        showarrow=False,
                        xref="paper", yref="paper",
                        x=0.005, y=-0.002)],
                    xaxis=dict(showgrid=False, zeroline=False, showticklabels=False),
                    yaxis=dict(showgrid=False, zeroline=False, showticklabels=False)))

# 显示关系图
fig.show()

这段代码会绘制一个包含 200 个节点和较多条边的复杂关系图，并设置节点和边的样式，最后显示关系图。你可以根据自己的需求修改节点和边的样式，或者使用其他库进行绘制。
