A standard wiki of charts: CKB

[arranzeyuwang]

Chart Knowledge Base (CKB) is a library that offers a knowledge base for chart wikis in a JSON format. We aim to build a standard wiki for every type of visualizations. You don't have to struggle with different names or alias or definition of a same chart type via CKB.

CKB enables users to quickly build their own chart dictionary product like ChartCube. Besides, with AVA 2.0, you'll be able to easily build a chart recommendation system with CKB and your customized rules.

A typical CKB JSON is like this:

{
  line_chart: {
    id: 'line_chart',
    name: 'Line Chart',
    alias: ['Lines'],
    family: ['LineCharts'],
    def: 'A line chart uses lines with segments to show changes in data in a ordinal dimension.',
    purpose: ['Comparison', 'Trend', 'Anomaly'],
    coord: ['Cartesian2D'],
    category: ['Statistic'],
    shape: ['Lines'],
    dataPres: [
      { minQty: 1, maxQty: 1, fieldConditions: ['Time', 'Ordinal'] },
      { minQty: 0, maxQty: 1, fieldConditions: ['Nominal'] },
      { minQty: 1, maxQty: 1, fieldConditions: ['Interval'] },
    ],
    channel: ['Position', 'Direction'],
    recRate: 'Recommended',
  },

  ...
}
