How can I create interactive dashboards using Dash and Plotly?

You can create interactive dashboards using Dash by defining your layout and callbacks. Would you like a simple example?

Yes, please provide a basic example of a Dash app.

Sure! Here's a simple example:

import dash
import dash_core_components as dcc
import dash_html_components as html
from dash.dependencies import Input, Output

app = dash.Dash(__name__)

app.layout = html.Div([
    dcc.Dropdown(
        id='dropdown',
        options=[{'label': 'Option 1', 'value': '1'}, {'label': 'Option 2', 'value': '2'}],
        value='1'
    ),
    html.Div(id='output')
])

@app.callback(Output('output', 'children'), [Input('dropdown', 'value')])
def update_output(value):
    return f'You have selected option {value}'

if __name__ == '__main__':
    app.run_server(debug=True)

This code creates a dropdown that updates a text output based on the selected option.

What libraries do I need to install to run this example?

You need to install Dash and its components. You can do this using pip:

pip install dash
