Lots of error when runing from sample notebook

[nssidhu]

I am running the code in Microsoft Fabric Notbook

Generate visualization via a "user query"

user_query = "What is the average price of cars by type?"
textgen_config = TextGenerationConfig(n=1, temperature=0.2, use_cache=True)
charts = lida.visualize(summary=summary, goal=user_query, textgen_config=textgen_config)  
charts[0]

import seaborn as sns
import pandas as pd
import matplotlib.pyplot as plt

Error-----
def plot(data: pd.DataFrame):
    # solution plan
    # i. group the data by Type and calculate the mean of Retail_Price
    # ii. plot the grouped data using a barplot
    sns.barplot(x='Type', y='Retail_Price', data=data.groupby('Type').mean().reset_index())
    plt.title('What is the average price of cars by type?', wrap=True)
    return plt;

chart = plot(data)
