Prompt:
What does this code do?
```python
class JsonOptions(PipelineOptions):
    @classmethod
    def _add_argparse_args(cls, parser):
        parser.add_argument(
            '--file_path',
            default="gs://your-bucket/your-file.json",
            help='Json file path'
        )

options = JsonOptions()

with beam.Pipeline(options=options) as p:
    output = (p | "Read from Json file" >> ReadFromJson(
        path=options.file_path,
        lines=False
        )
        | "Log Data" >> Map(logging.info))
```
Response:
This code reads data from a [JSON file](https://www.json.org/) using the `ReadFromJson` transform from the built-in [TextIO connector](https://beam.apache.org/releases/pydoc/current/apache_beam.io.textio.html).

```python
class JsonOptions(PipelineOptions):
    @classmethod
    def _add_argparse_args(cls, parser):
        parser.add_argument(
            '--file_path',
            default="gs://your-bucket/your-file.json",
            help='Json file path'
        )

options = JsonOptions()

```
The `JsonOptions` class is used to define the command-line argument `--file_path`, which specifies the path to the JSON file. This code uses [pipeline options](https://beam.apache.org/documentation/patterns/pipeline-options/) for the required `file_path` argument.

```python
with beam.Pipeline(options=options) as p:
    output = (p | "Read from Json file" >> ReadFromJson(
        path=options.file_path,
        lines=False
        )
        | "Log Data" >> Map(logging.info))
```
A Beam pipeline is created using the `JsonOptions` class and the `ReadFromJson` transform is used to read data from the JSON file. The `lines` parameter is set to `False` to read the entire file as a single JSON object.
