Visualization Reporter

This directory contains a reporter, that can be used to visualize how the resolution algorithm is exploring the dependency graph, by exposing the information about the process that is being provided by the reporter.

Usage

There's 2 ways to try out the reporter defined in this directory:

With run.py, based on an output from reporter_demo.py. This demonstrates how to "record" a resolution run, and "play it back" later to generate the visualization.
```
$ # In the examples/ directory
$ python reporter_demo.py > foo.txt
$ python visualization/run.py foo.txt out.html
...
```
With run_pypi.py, that uses the pypi_wheel_provider.py example code. This demonstrates how a visualization can be generated while running the resolver.
```
$ # In the examples/ directory
$ python visualization/run_pypi.py out.html
...
```

NOTE: This code mainly serves to demonstrate what can be done with resolvelib's Reporter API. It likely contains bugs and there's definitely a lot of scope for improvement here (more interactive visualization, making it easier to look at and work with larger dependency graphs and more).
