[Seaborn][matplotlib]Pythonのseaborn散布図プロットで各点にラベルをつける方法

import pandas as pd
import numpy as np
from matplotlib import pylab as plt
import japanize_matplotlib
import seaborn as sns
sns.set(font = "IPAexGothic")
plt.style.use("seaborn-whitegrid")

tips = sns.load_dataset("tips")[:30]
#図が煩雑になるので最初の30データだけ読み込み

tips["ID"] = np.arange(len(tips))
tips.ID = tips.ID.astype(str)
#文字型に変換

def label_point(x,y,id,ax):
  df_tmp=pd.concat({'x':x,'y':y,'id':id}, axis='columns')
  for i, point in df_tmp.iterrows():
    ax.text(point['x'], point['y'], point['id'],\
    fontsize=10\
    )
ax = sns.scatterplot(x = "total_bill", y = "tip", data = tips)
label_point(tips["total_bill"], tips["tip"], tips["ID"], ax)
