setup() is called to start the process and finish() is called afterwards.
This class is set up to provide for writing movie frame data to a pipe. saving() is provided as a context manager to facilitate this process as:
with moviewriter.saving(fig, outfile='myfile.mp4', dpi=100):
# Iterate over frames
moviewriter.grab_frame(**savefig_kwargs)
The use of the context manager ensures that setup() and finish() are performed as necessary.
An instance of a concrete subclass of this class can be given as the writer
argument of :None:None:`Animation.save()`.
Abstract base class for writing movies. Fundamentally, what a MovieWriter does is provide is a way to grab frames by calling grab_frame().
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
