提取结构化数据并进行特征清洗与聚类分析，生成包含趋势对比、分布特征与参数敏感性的多维度综合可视化图表，适用于各类趋势预测与多维对比场景。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Step1 数据加载与预处理（支持大文件Parquet转换与动态表头识别）。
```python
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns
from sklearn.cluster import KMeans
from sklearn.preprocessing import StandardScaler
import os
import re
# 设置中英文字体与图表美化
plt.rcParams['font.sans-serif'] = ['SimHei', 'WenQuanYi Zen Hei', 'DejaVu Sans']
plt.rcParams['axes.unicode_minus'] = False
file_path = 'input_data.xlsx'
# 处理大型Excel文件：统计总行数，若≥1万则转换为Parquet格式提升效率
xls = pd.ExcelFile(file_path)
total_rows = sum(pd.read_excel(xls, sheet_name=s, header=None).shape[0] for s in xls.sheet_names)
if total_rows >= 10000:
parquet_path = "temp_converted_file.parquet"
with pd.ExcelWriter(parquet_path, engine='pyarrow') as writer:
for sheet in xls.sheet_names:
df_sheet = pd.read_excel(xls, sheet_name=sheet, header=None)
df_sheet.to_excel(writer, sheet_name=sheet, index=False, header=False)
df = pd.read_excel(parquet_path, sheet_name='Sheet1', header=None)
else:
df = pd.read_excel(file_path, sheet_name='Sheet1', header=None)
# 动态识别表头并提取数据
header_row_idx = None
target_cols = ['group_col', 'value_col1', 'value_col2'] # 占位示例列名

How to install
mdr add opensensenova/sensenova-skills/line-chart-visualization@sha256:4d39e2ff4c04fdf8The line at the top of this page pins the label git:20260426.f0ab496, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
