# 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:
1. 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.
```sh-session
$ # In the examples/ directory
$ python reporter_demo.py > foo.txt
$ python visualization/run.py foo.txt out.html
...
```
2. 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.
```sh-session
$ # 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).
