In this example, we'll write a brand new tool called gen-data that will generate random data using Polygraphy's default data loader, and then write it to an output file. The user will be able to specify the number of values to generate as well as the output path.

To do this, we'll create a child class of Tool and use the DataLoaderArgs argument group provided by Polygraphy.

Running The Example

You can run the example tool from this directory. For example:
```
./gen-data -o data.json --num-values 25
```
We can even inspect the generated data with inspect data:
```
polygraphy inspect data data.json -s
```

To see the other command-line options available in the example tool, run:

./gen-data -h
