_get_index(names, key)
The key
can be an integer or string. If integer, it is the index in the list. If string,
Field (column) names are case sensitive: you can have two different columns called 'abc' and 'ABC' respectively.
When you refer to a field (presumably with the field method), it will try to match the exact name first, so in the example in (a), field('abc') will get the first field, and field('ABC') will get the second field.
If there is no exact name matched, it will try to match the name with case insensitivity. So, in the last example, field('Abc') will cause an exception since there is no unique mapping. If there is a field named "XYZ" and no other field name is a case variant of "XYZ", then field('xyz'), field('Xyz'), etc. will get this field.

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
