        "type": "circle",
        "source": {
            "type": "vector",
            "tiles": ["https://halsk.github.io/pharmacies-tiles/zxy/{z}/{x}/{y}.pbf"],
            "maxzoom": 14
        },
        "source-layer": "pharmacies",
        "paint": {
            // make circles larger as the user zooms from z12 to z22
            'circle-radius': 5,
            "circle-stroke-width": 1,
            // color circles by ethnicity, using a match expression
            'circle-color': [
                "case",
                [
                    ">",
                    ["get", "mask_adult"],
                    200

About data

The data itself is located in the gh-pages branch and hosted by the GitHub Pages function.

This vector tile is based on @kiang's GeoJson file.

• GeoJson: https://raw.githubusercontent.com/kiang/pharmacies/master/json/points.json
• GitHub: https://github.com/kiang/pharmacies

The @kiang's data is created from Taiwan government data. The original data source is updated every 30 seconds. And this repository's files are updated every five minutes by CircleCI. (But I'm not sure if the data is actually refreshed.)

Please see details here about this datasets.
