It ends up inheriting functions which are not applicable to it (selectRow, selectCol, etc).

I am very happy to get help from you

@MarkKoz I just published the documentation for tracers.js (and also revised Randomize functions): https://algorithm-visualizer.github.io/tracers.js/. Let me know if you need anything else!

Quote from Python's json module documentation:

This module does not comply with the RFC in a strict fashion, implementing some extensions that are valid JavaScript but not valid JSON. In particular:

• Infinite and NaN number values are accepted and output;

This is a problem because JavaScript's JSON parser will consider values such as Infinity (note this is not a string) as invalid.

A custom JSONEncoder can be used to address these issues, but the question remains to what these values should be serialised. What format will allow JavaScript to properly interpret them? Oddly enough, JS itself serialises Infinity to null so that's not an answer.

Some parameters may have been removed. Basing off the changes in algorithm-visualizer/tracers.js@15cf992

For example, visitedCount and selectedCount of GraphTracer.addNode() are gone.
