Parameters

arr : array-like

The values to be converted to str, if needed.

na_value : Any, default np.nan

The value to use for na. For example, np.nan or pd.NA.

convert_na_value : bool, default True

If False, existing na values will be used unchanged in the new array.

copy : bool, default True

Whether to ensure that a new array is returned.

skipna : bool, default True

Whether or not to coerce nulls to their stringified form (e.g. if False, NaN becomes 'nan').

Returns

np.ndarray[object]

An array with the input array's elements casted to str or nan-like.

Returns a new numpy array with object dtype and only strings and na values.

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
