graphviz_sink

Outputs the events considering it as a Graphviz graph.

Parameters

gif_path: str default: None
The path where the gif of the stream should be stored. If None is specified, then the output is rendered on the notebook directly.
fps: int default: 5
The number of frame per seconds, in case the output is stored as a GIF.
mode: str default RGB
The GIF color mode.
bg_color: tuple default: (255, 255, 255)
The background color of the GIF.
center: boolean default: True
Whether the content should be centered.

Example

from pybeamline.sources import string_test_source
from pybeamline.algorithms.discovery.dfg_miner import simple_dfg_miner
from pybeamline.mappers.dfg_str_to_graphviz import dfg_str_to_graphviz
from pybeamline.sinks.graphviz_sink import graphviz_sink

log_original = ["ABCD"]*50 + ["ACBD"]*50
log_after_drift = ["AEFG"]*50 + ["AFEG"]*50

string_test_source(log_original + log_after_drift).pipe(
    simple_dfg_miner(model_update_frequency=50, min_relative_frequency=0.2),
    dfg_str_to_graphviz(),
).sink(graphviz_sink(gif_path='test_graphviz_sink.gif', fps=1))

Output:
