_check_data_length(self, columns: 'Sequence[Hashable]', data: 'Sequence[ArrayLike]') -> 'None'

One set of trailing commas is allowed. self.index_col not False results in a ParserError previously when lengths do not match.

Parameters

columns: list of column names :

data: list of array-likes containing the data column-wise. :

Checks if length of data is equal to length of column names.

Examples

See :

Local connectivity graph

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
