fileobj_open(filename, mode)
This exists because :None:None:`open()` returns an io.BufferedReader
by default. This is bad, because io.BufferedReader
doesn't support random access, which we need in some cases. We must call open with buffering=0 to get a raw random-access file reader.
A wrapper around the :None:None:`open()` builtin.
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
