Very confused. “Viridis” is available, but not mentioned in the documentation. There is a link https://plot.ly/ipython-notebooks/color-scales/ that shows a lot of color scales, but since it’s missing Viridis, I don’t know what else it’s missing.
And also I couldn’t figure out what plotly uses as a default color scale for a marker / line / etc. (does it depend on the context?).
