The line is overflow like this. How can fix this

The chart right like this

```
import numpy as np
import streamlit as st;
from matplotlib import pyplot as plt
from sklearn.linear_model import LinearRegression
import pandas as pd
import altair as alt
def main():
X = np.random.rand(1000)
y = 4 + 3 * X + .5*np.random.randn(1000)
z = "blue"
st.expander("Show data").write(pd.DataFrame({"x":X,"y":y,"z":z,"t":2}))
c = (
alt.Chart(pd.DataFrame({"x":X,"y":y,"z":z,"t":2}))
.mark_circle(size=50)
.encode(
x="x:Q",
y="y:Q",
color = alt.Color("z", scale=None),
)
)
# Chuyen mang 1 chieu thanh vector
X = np.array([X])
y = np.array([y])
# Chuyen vi ma tran
X = X.T
y = y.T
model = LinearRegression()
model.fit(X, y)
w0 = model.intercept_
w1 = model.coef_[0]
x0 = 0
y0 = w1*x0 + w0
x1 = 1
y1 = w1*x1 + w0
lines = (
alt.Chart(pd.DataFrame({"x": [x0, x1], "y": [y0, y1],}))
.mark_line()
.encode(x="x", y="y")
)
st.altair_chart(c+lines, use_container_width=True)
if __name__ == '__main__':
main()
```
