How can I add annotations to my Plotly Dash app?

You can add annotations in Plotly Dash by using the annotations attribute in your layout. Would you like a code example?

Yes, please provide a code example.

Sure! Here's a simple example:

import dash
import dash_core_components as dcc
import dash_html_components as html
import plotly.graph_objs as go

app = dash.Dash(__name__)

app.layout = html.Div([
    dcc.Graph(
        id='example-graph',
        figure={
            'data': [go.Scatter(x=[1, 2, 3], y=[4, 5, 6])],
            'layout': go.Layout(
                annotations=[
                    dict(x=2, y=5, text='Annotation', showarrow=True)
                ]
            )
        }
    )
])

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

What do the parameters in the annotations dictionary mean?

The annotations dictionary can include parameters like x, y for position, text for the annotation text, and showarrow to display an arrow pointing to the annotation.
