3d plot data not rendering

Hello -

I am trying to plot a 3d surface using the python API. I an get the axis to render but the data is not showing up. Suggestions?

plot = go.Mesh3d(
    
    x = biden2['Age'],
    y = biden2['Education'],
    z = biden2['Predicted_Biden'],
    opacity = .75,
    color = "rgb(39, 100, 0)"
)

layout = go.Layout(
                    scene = dict(
                    xaxis = dict(
                        title='Age'),
                    yaxis = dict(
                        title='Education'),
                    zaxis = dict(
                        title='Biden'),),
                    width=700,
                    margin=dict(
                    r=20, b=10,
                    l=10, t=10)
                  )


fig = go.Figure(data = [plot], layout = layout)

py.iplot(fig)
