Koto Config (WIP)

This is an optional decorator for KotoJS charts that allows chart authors to specify a validation schema (using JSON-SCHEMA). Attempting to set a property that is not valid will throw an Error.

Example Usage

// JSON SCHEMA
const schema = {
  height: {
    type: 'number',
    minimum: 500,
    default: 500
  },
  fill: {
    type: 'color',
    default: '#fff'
  }
};

@KotoConfig(schema)
class Chart extends Koto {
  preDraw() {
    console.log('predraw');
  }
}

const chart = new Chart(d3.select(document.body));
chart.config('height', 400); // => throws Error with message
chart.config('fill', 'steelblue'); // valid
