[Python] Is it possible to increase the space between trace lines that are overlapping on the...

I have been searching for this solution in the official site of Plotly, Plotly forum and this forum for 3 days, and did not find it. I tried these following quetsions:

• How to avoid overlapping text in a plotly scatter plot?
• Make X axis wider and Y axis narrower in plotly

For example, here is the image:



You can see that Angola’s, Cabo Verde’s, Mozambique’s, Portugal’s, and São Tomé’s trace lines are overlapping each other on the Y-axis. On the X-axis, these markers of the numbers of population of all these countries between the years 2022 and 2025 are overlapping each other.

Here is the CSV data:

"Country","2022","2024","2025","2030","2040","2050"
"Angola","35.6M","37.9M","39M","45.2M","59M","74.3M"
"Brasil","210M","212M","213M","216M","219M","217M"
"Cabo Verde","520K","525K","527K","539K","557K","566K"
"Moçambique","32.7M","34.6M","35.6M","40.8M","52.1M","63.5M"
"Portugal","10.4M","10.4M","10.4M","10.3M","10.1M","9.8M"
"São Tomé and Príncipe","226K","236K","240K","265K","316K","365K"


And here is the simple and small code:

import pandas as pd
import plotly.express as px
import plotly.graph_objects as go

fig = go.Figure()
df = pd.read_csv('assets/csv/luso_pop_proj_who_data.csv')

for col in df.columns[1:]:
df[col] = df[col].replace({"M": "e+06", "K": "e+03"}, regex = True).astype(float)

df_long = df.melt(id_vars = "Country", var_name = "Year", value_name = "Population")
df_long["Year"] = df_long["Year"].astype(int)

fig = px.line(
df_long,
color = "Country",
height = 600,
labels =
{
"Country": "País",
"Population": "Número de população",
"Year": "Ano"
},
template = "seaborn",
text = "Population",
title = "Projeção da população nos países lusófonos (2022-2050)",
width = 1200,
x = "Year",
y = "Population",
)

fig.update_traces(
hovertemplate = None,
mode = "lines+markers+text",
showlegend = True,
textfont = dict(size = 15),
textposition = "top center",
texttemplate = "%{text:.3s}",
)

fig.update_layout(
margin = dict(l = 0, r = 0, b = 10, pad = 0),
hovermode = False
)

fig.show(
config = config
)


I have been testing with these following codes:

fig = px.line(
facet_row_spacing = 1,
)

fig.update_traces(
line = dict(
backoff = 10,
),
)

fig.update_xaxes(
automargin = True,
autorange = False,
fixedrange = True,
range = ['2020', '2050'],
)

fig.update_yaxes(
automargin = True,
fixedrange = True,
)

fig.update_layout(
margin = dict(l = 0, r = 0, b = 10, pad = 0),
)


I expected that, with these configurations, the trace lines moved away with the increasing space, but it did not give any effect.
