[Python] x and y axis not displaying in chart created by openpyxl

I am trying to use openpyxl to automate the creation of graphs in excel. However, the charts that are being produced are not generating axes when I run the code on my machine.

I am using the example code for creating a scatter plot found here.

My graph looks like this:

My coworker ran the same code on their computer and it displayed correctly. Could it be an issue with the way Python is installed?

I am using Python 3.13.0 and version 3.1.5 of openpyxl although I have also tried version 3.1.2 based on an older question with no luck.

from openpyxl import Workbook
from openpyxl.chart import (
ScatterChart,
Reference,
Series,
)

wb = Workbook()
ws = wb.active

rows = [
['Size', 'Batch 1', 'Batch 2'],
[2, 40, 30],
[3, 40, 25],
[4, 50, 30],
[5, 30, 25],
[6, 25, 35],
[7, 20, 40],
]

for row in rows:
ws.append(row)

chart = ScatterChart()
chart.title = "Scatter Chart"
chart.style = 13
chart.x_axis.title = 'Size'
chart.y_axis.title = 'Percentage'

xvalues = Reference(ws, min_col=1, min_row=2, max_row=7)
for i in range(2, 4):
values = Reference(ws, min_col=i, min_row=1, max_row=7)
series = Series(values, xvalues, title_from_data=True)
chart.series.append(series)

ws.add_chart(chart, "A10")

wb.save("scatter.xlsx")
