 ### Built-In Sequential Color scales
 
 A collection of predefined sequential colorscales is provided in the `plotly.colors.sequential` module. Sequential color scales are appropriate for most continuous data, but in some cases it can be helpful to use a diverging or cyclical color scale (see below).

 By default, the resulting HTML file is a fully self-contained HTML file which can be uploaded to a web server or shared via email or other file-sharing mechanisms. The downside to this approach is that the file is very large (5Mb+) because it contains an inlined copy of the Plotly.js library required to make the figure interactive. This can be controlled via the `include_plotlyjs` argument (see below).

 When you have more than 2 classes, you will need to plot the ROC curve for each class separately. Make sure that you use a [one-versus-rest](https://scikit-learn.org/stable/modules/multiclass.html#one-vs-the-rest) model, or make sure that your problem has a [multi-label](https://scikit-learn.org/stable/modules/multiclass.html#multilabel-classification-format) format; otherwise, your ROC curve might not return the expected results.
