Hi  
I wonder if someone have managed to run a Dash page with a Plotly express chart on Heroku? If that is the case, could you provide me with a simple example?

This is what I tried:  
import dash  
import dash\_core\_components as dcc  
import dash\_html\_components as html  
import plotly\_express as px  
import pandas as pd

```
df = pd.read_csv('2011_us_ag_exports.csv')

app = dash.Dash()
server = app.server

app.layout = html.Div(
    html.Div([
        dcc.Graph(figure=px.scatter(df, x="beef", y="pork")
    ])
)

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

```

I’d be happy to try to help! Did what you tried not work? If so, why not, what happens?

You are missing a ) at the end of the Graph component.

app.layout = html.Div(  
html.Div([  
dcc.Graph(figure=px.scatter(df, x=“beef”, y=“pork”))  
])  
)

On a side note, all the heroku apps I have using px do not create the figure in the layout. I have the figure in a callback or create a def. Shouldn’t matter but as the apps get larger you will be thankful.
