app.layout = html.Div(children=[

I can help only by sharing what I’d do in that situation.
First inspect page in your browser and try to figure out where margin-bottom comes from.
Try to eliminate margin in style/css file.
Tinker with plotly layout settings.
Also try to zoom out with the page - if margin disappears then you have some element that is carried over below the graph. (can be done while inspecting the page while in a browser)

Hope this helps.
