Package for Easily Generating Scatter Plots & Line Graphs using D3

Basic Usage:

  • npm install -S scatter-plot-d3

  • import in code

    • import 'd3Scatter from 'scatter-plot-d3'

  • Add canvas element to html page (d3Canvas is the default id expected)

    • <div id='#d3Canvas' />

  • Call addScatter

    • const data_example = [{country: 'USA', gdp: 20.8, population: 331}, {country: 'China', gdp: 14.9, population: 1406}, {country: 'Japan', gdp: 4.9, population: 126}, {country: 'Germany', gdp: 3.8, population: 83}, {country: 'France', gdp: 2.6, population: 67}]
    • d3Scatter.addScatter({data: data, xCol: 'gdp', yCol: 'population'})

Options:

  • specify canvas size (defaults to 900 x 600)

    • (automatically adjusts size to fit canvas)
    • d3Scatter({data: data, xCol: 'population', yCol: 'gdp', canvasHeight: 500, canvasWidth: 800})

  • add line / curve

    • d3Scatter({data: data, line: true})
    • d3Scatter({data: data, curve: true})

  • specify axis labels

    • (automatically adjusts size to fit canvas)
    • d3Scatter({data: data, xCol: 'population', yCol: 'gdp', xaxis: 'population (in Millions)', yaxis: 'GDP ($USD in millions)'})

  • specify scale

    • (overrides auto-scaling that fits plot to canvas size)
    • d3Scatter({data: data, scale: 0.2})

  • check default settings

    • var defaults = d3Scatter.checkDefaults()
    • this allows you to check values like 'scale', 'maxValue' etc. if you have customized the canvas size and/or scaling
    • var defaults = d3Scatter.checkDefaults({data: data, scale: 10, canvasHeight: 500, canvasWidth: 800})

  • embed data table in page

    • add empty element in html
    • <div#embedDataHere />
      • d3Scatter.addScatter({data: data, embedData: "embedDataHere"})
