I am not understanding the reason why range on y_axis goes more than around 500k whereas the max value for the column Total_Expenditure 2486. What is the reason of being the value at y axis goes over 500k?
What is the underlying thing going on here or explanation behind it?

import plotly.express as px
import plotly.io as pio

barchart = px.bar(
data_frame = data,
x = 'Education',
y = 'Total_Expenditure',
color = 'labels3',
barmode ='group',
title='Relationship of Transaction and Education',
width= 900, height= 500,
template= 'plotly_dark'),

barchart.update_traces(marker_line_width = 0,selector=dict(type="bar"))

pio.show(barchart)

I tried to find the reason in different platform. I think the reason is so simple and too basic but i could not figure it out it.
