start_year = st.slider('Start year:', min(df['year']), max(df['year']))
end_year = st.slider('End year:', min(df['year']), max(df['year']))

# Filter the data
df_filtered = df[df['year'] >= start_year]
df_filtered = df_filtered[df_filtered['year'] <= end_year]

# Create a callback function to update the line chart when the slider values change
def update_line_chart():
    st.line_chart(df_filtered['column_name_1'], df_filtered['column_name_2'])

# Call the callback function when the slider values change
st.on_change('start_year', update_line_chart)
st.on_change('end_year', update_line_chart)

# Update the line chart
update_line_chart()

This application will create a line chart that displays the data for the two selected columns. When the user changes the slider values, the callback function will be called to update the line chart with the new data.

Sure. Here is an example of a basic Streamlit application that generates a simple bar chart from a dataset:

import streamlit as st
import pandas as pd

# Load the dataset
df = pd.read_csv('dataset.csv')

# Select the data for the chart
x = df['column_name_1']
y = df['column_name_2']

# Create the bar chart
st.bar_chart(df, x, y)

To run this application, save it as a Python file (e.g. app.py) and then run the following command in a terminal:

streamlit run app.py

This will open a web browser with the Streamlit application. You should see a bar chart with the data from the dataset.

You can customize the bar chart by changing the parameters of the st.bar_chart() function. For example, you can change the title of the chart, the labels for the x and y axes, and the colors of the bars.

Here is an example of a customized bar chart:

import streamlit as st
import pandas as pd

# Load the dataset
df = pd.read_csv('dataset.csv')

# Select the data for the chart
x = df['column_name_1']
y = df['column_name_2']

# Create the bar chart
st.bar_chart(
    df,
    x,
    y,
    title='My Bar Chart',
    xlabel='X Axis',
    ylabel='Y Axis',
    colors=['red', 'green', 'blue']
)

This will create a bar chart with the title My Bar Chart, the x-axis label X Axis, the y-axis label Y Axis, and the bars colored red, green, and blue.

You can also add interactive widgets to your Streamlit applications. For example, you could add a drop-down menu that allows users to select different data columns to visualize in the chart.

Here is an example of a Streamlit application with a drop-down menu:

import streamlit as st
import pandas as pd

# Load the dataset
df = pd.read_csv('dataset.csv')

# Create a drop-down menu
column_name = st.selectbox('Select a column to visualize:', df.columns)

# Select the data for the chart
x = df[column_name]

# Create the bar chart
st.bar_chart(x)

This will create a Streamlit application with a drop-down menu that allows users to select different data columns to visualize in the chart. When the user selects a column, the chart will be updated to show the data for that column.

Streamlit is a powerful and easy-to-use tool for creating interactive data applications. You can use it to create a wide variety of applications, from simple data visualizations to complex dashboards to machine learning models.
