Make plotly graph vertical

I have a graph with a horizontal axis:

How can I make the axis vertical so it can be more readable?

app = dash.Dash(__name__, external_stylesheets=external_stylesheets)

df = pd.read_csv("cb_pb.csv", index_col=0)

app = dash.Dash(__name__, external_stylesheets=external_stylesheets)
app.layout = html.Div([

    html.Div([
        dcc.Graph(id='the_graph')
    ])
])

@app.callback(
    Output(component_id='the_graph', component_property='figure'),
    [Input(component_id="perfume-dropdown", component_property="value")]
)
def update_graph(my_dropdown):
    dfc = df.sort_values(by='perceived_benefit', ascending=False)
    traces = []
    for i in range(len(dfc)):
        if dfc.iloc[i].name == my_dropdown:
            trace_claimed = go.Bar(x=[dfc.iloc[i].values[0]], y=[dfc.iloc[i].values[2]], name='Claimed')
            trace_perceived = go.Bar(x=[dfc.iloc[i].values[0]], y=[-dfc.iloc[i].values[1]], name='Perceived')
            traces.append(trace_claimed)
            traces.append(trace_perceived)
    figure={
        'data': traces,
        'layout':
            go.Layout(title='Score des parfums sur les attributs', barmode='stack')
    }

    return figure

Add to the go.bar(
