        "url": "data/cars.json"

    },

    "mark": "bar",

    "encoding": {

        "x": {

            "field": "Horsepower",

            "type": "quantitative"

        },

## Credits

Vega-lite-linter was invented by the [iDVx Lab](https://idvxlab.com/) together with [AntV](https://antv.vision/en). 

Based on our technology, [AntV](https://antv.vision/en) and [iDVx Lab](https://idvxlab.com/) also developed [ChartLinter](https://ava.antv.vision/en/docs/guide/chart-linter/intro) in Javascript to support visualization charts beyond Vega-Lite.
