What's the difference btw `plotly.graph_objects.Scatter` and `plotly.graph_objects.scatter`?

As shown in the image below, there are two pages for the reference on plotly.graph_objects.scatter, one with an upper-case S, and the other with a lower-case s.

May I ask what the differences btw them are?

Lowercase corresponds to the module


go.Figure(go.Scatter(x=[0,1, y=[0,1]))

go.Figure(go.scatter(x=[0,1, y=[0,1]))

the latter will throw the error

TypeError: 'module' object is not callable
