Distance between categories on x-axis

Is there a way to decrease the white space between Sat and Sun on the x-axis?
(Data here https://www.dropbox.com/s/iht1ogn9il0t42m/tips_1.xlsx?dl=0)

import plotly.express as px
import pandas as pd

df = pd.read_excel('/Users/Jakob/Documents/python_notebooks/data/tips_1.xlsx')

fig = px.scatter(df, x='day', y='total_bill', color="day")

#  Customization of y-axis
#fig.update_yaxes(range=[0, 10])

# Figure layout
fig.update_layout(template='simple_white',  title='Main Title', yaxis_title='Distance moved',
                  legend=dict(title='', itemclick='toggle', itemsizing='constant', traceorder='normal',
                  bgcolor='rgba(0,0,0,0)', x=1),
                  xaxis=dict(title='This is a title', showticklabels=True, ticks='outside', type='category')
                 )

fig.show()

Something like width=300 does the trick.

# Figure layout
fig.update_layout(template='simple_white', width=300, height=500, title='Main Title', yaxis_title='Distance moved',
                  legend=dict(title='', itemclick='toggle', itemsizing='constant', traceorder='normal',
                  bgcolor='rgba(0,0,0,0)', x=1),
                  xaxis=dict(title='This is a title', showticklabels=True, ticks='outside')
                 )
