colorScale property
The color scale for data cells in the treemap chart.
Data cells are assigned colors based on their color values. These color values come from color_data, or from size_data if color_data is not specified. Cells with color values less than or equal to min_value will have minValueColor as their background color. Cells with color values greater than or equal to max_value will have maxValueColor as their background color. Cells with color values between min_value and max_value will have background colors on a gradient between minValueColor and maxValueColor, the midpoint of the gradient being midValueColor. Cells with missing or non-numeric color values will have noDataColor as their background color.
