# data/filter — Interactive dataset browser and filter

Browse a `StructuredDataset`, visualize the selected image and keypoint, and
optionally delete entries interactively.

## Usage

```bash
s6 data filter ./path/to/dataset \
  --image-key B/image --point-key B/tip_point
```

## Controls
- `a`/`d` — previous/next entry
- `x` — delete current entry
- `q` — quit

## How it works
- Loads the dataset with `s6.utils.StructuredDataset` and pulls nested fields
  via a slash-delimited datakey accessor.
- Draws a keypoint cross using `s6.vision.drawing.Markers` and shows a zoomed
  crop around the keypoint for precision.
- Deletions call `StructuredDataset.delete_one(index)` and update the view.
