timeseries(start='2000-01-01', end='2000-01-31', freq='1s', partition_freq='1d', dtypes={'name': <class 'str'>, 'id': <class 'int'>, 'x': <class 'float'>, 'y': <class 'float'>}, seed=None, **kwargs)

Parameters

start : datetime (or datetime-like string)

Start of time series

end : datetime (or datetime-like string)

End of time series

dtypes : dict

Mapping of column names to types. Valid types include {float, int, str, 'category'}

freq : string

String like '2s' or '1H' or '12W' for the time series frequency

partition_freq : string

String like '1M' or '2Y' to divide the dataframe into partitions

seed : int (optional)

Randomstate seed

kwargs: :

Keywords to pass down to individual column creation functions. Keywords should be prefixed by the column name and then an underscore.

Create timeseries dataframe with random data

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
