This dtype implements the pandas ExtensionDtype interface.
The dtype of the underlying array storing the non-fill value values.
The scalar value not stored in the SparseArray. By default, this depends on dtype
.
=========== ========== dtype na_value =========== ========== float np.nan
int 0
bool False
datetime64 pd.NaT
timedelta64 pd.NaT
=========== ==========
The default value may be overridden by specifying a :None:None:`fill_value`.
Dtype for data stored in SparseArray

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
