Yes, Xlsxwriter[docs][pypi] has a lot of utility for creating excel charts in Python. You will need to however use the an xlsx file format, there is not much feedback for incorrect parameters, and you cannot read your output.

import xlsxwriter
import random
# Example data
# Try to do as much processing outside of initializing the workbook
# Everything beetween Workbook() and close() gets trapped in an exception
random_data = [random.random() for _ in range(10)]
# Data location inside excel
data_start_loc = [0, 0] # xlsxwriter rquires list, no tuple
data_end_loc = [data_start_loc[0] + len(random_data), 0]

workbook = xlsxwriter.Workbook('file.xlsx')

# Charts are independent of worksheets
chart = workbook.add_chart({'type': 'line'})
chart.set_y_axis({'name': 'Random jiggly bit values'})
chart.set_x_axis({'name': 'Sequential order'})
chart.set_title({'name': 'Insecure randomly jiggly bits'})

worksheet = workbook.add_worksheet()

# A chart requires data to reference data inside excel
worksheet.write_column(*data_start_loc, data=random_data)
# The chart needs to explicitly reference data
chart.add_series({
    'values': [worksheet.name] + data_start_loc + data_end_loc,
    'name': "Random data",
})
worksheet.insert_chart('B1', chart)

workbook.close()  # Write to file
