Mapping(required=[name])

- namestring
A color scheme name for ordinal scales (e.g.,
"category10"or"blues").For the full list of supported schemes, please refer to the Vega Scheme reference.

The number of colors to use in the scheme. This can be useful for scale types such as
"quantize", which use the length of the scale range to determine the number of discrete bins for the scale domain.- extentList(float)
The extent of the color range to use. For example
[0.2, 1]will rescale the color scheme such that color values in the range [0, 0.2) are excluded from the scheme.
