rgb2lab(rgb, illuminant='D65', observer='2')
This function uses rgb2xyz and xyz2lab. By default Observer= 2A, Illuminant= D65. CIE XYZ tristimulus values x_ref=95.047, y_ref=100., z_ref=108.883. See function get_xyz_coords
for a list of supported illuminants.
The image in RGB format. Final dimension denotes channels.
The name of the illuminant (the function is NOT case sensitive).
The aperture angle of the observer.
If :None:None:`rgb` is not at least 2-D with shape (..., 3).
The image in Lab format. Same dimensions as input.
RGB to lab color space conversion.

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
