Creating a Basic Sankey Chart

Creating a basic Sankey chart using ApexSankey.js

To create a basic sankey chart with minimal configuration, write the following HTML:

<div id="svg-sankey" style="display: flex; justify-content: center"></div>

Now, write the following in the script tag

const data = {
  nodes: [
    {
      id: 'Oil',
      title: 'Oil',
    },
    {
      id: 'Natural Gas',
      title: 'Natural Gas',
    },
    {
      id: 'Coal',
      title: 'Coal',
    },
    {
      id: 'Fossil Fuels',
      title: 'Fossil Fuels',
    },
    {
      id: 'Electricity',
      title: 'Electricity',
    },
    {
      id: 'Energy',
      title: 'Energy',
    },
  ],
  edges: [
    {
      source: 'Oil',
      target: 'Fossil Fuels',
      value: 15,
    },
    {
      source: 'Natural Gas',
      target: 'Fossil Fuels',
      value: 20,
    },
    {
      source: 'Coal',
      target: 'Fossil Fuels',
      value: 25,
    },
    {
      source: 'Coal',
      target: 'Electricity',
      value: 25,
    },
    {
      source: 'Fossil Fuels',
      target: 'Energy',
      value: 60,
    },
    {
      source: 'Electricity',
      target: 'Energy',
      value: 25,
    },
  ],
};
const graphOptions = {
  nodeWidth: 20,
  fontFamily: 'Quicksand, sans-serif',
  fontWeight: 600,

};
const s = new ApexSankey(document.getElementById('svg-sankey'), graphOptions);
