Datasette plugin that replaces any GeoJSON column values with a Leaflet map

## Installation

## Configuration

By default this plugin displays maps for the first ten rows, and shows a "Click to load map" prompt for rows past the first ten.

You can change this limit using the `default_maps_to_load` plugin configuration setting. Add this to your `metadata.json`:

```json
{
    "plugins": {
        "datasette-leaflet-geojson": {
            "default_maps_to_load": 20
        }
    }
}
```
Then run Datasette with `datasette mydb.db -m metadata.json`.
