sankey-plus v0.7.0

sankey-plus

NOT READY FOR USE YET - CONTAINS BUGS :)

A JavaScript library for computing and drawing Sankey graphs.

Based on the D3-Sankey and D3-Sankey-Circular(https://github.com/tomshanley/d3-sankey-circular) libraries, and the experiments in my Observable notebook.

This library enhances those to provide:

• Handling for circular links
• Routing of long links to avoid overlapping nodes
• Improved layout
• New API that uses a config object

API Reference

Import SankeyChart from sankeyPlus.js:

import { SankeyChart } from './sankeyPlus.js'

Create a new chart:

let chart = new SankeyChart(element, config);

• element: An HTML element, such as a DIV, which will contain the SVG element created by SankeyChart.draw()
• config: an options object containing the configuration for the sankey chart.

To render the chart, call the draw() method, which creates an SVG element in the specified HTML element:

chart.draw();

Config options:

The config options has the structure:

let config = {
    //main options
    nodes: {
        //data and options for nodes
    },
    links: {
        //data and options for links
    },
    arrows: {
        //data and options for links
    }
}
