x_days = list(range(1, 11))
stock_a = [50, 52, 51, 55, 60, 58, 62, 65, 64, 70]
stock_b = [40, 41, 45, 43, 48, 50, 53, 52, 55, 59]

line_data = [
    {'y_data': stock_a, 'line_color': 'green', 'marker_style': 'o'},
    {'y_data': stock_b, 'line_color': 'red', 'marker_style': 'x'}
]

chart.Line(
    chart_title='Stock Price Comparison Over 10 Days',
    x_data=x_days,
    y_data_sets=line_data,
    data_labels=['Stock A', 'Stock B'],
    x_label='Trading Day',
    y_label='Price ($)',
)

# 4. Scatter Plot Example: Correlation

x_hours = [1, 2, 3, 4, 5, 6, 7, 8]
y_score = [55, 60, 68, 75, 80, 85, 90, 95]

chart.Scatter(
    chart_title='Study Hours vs. Exam Score',
    x_data=x_hours,
