ES6 d3.js parallel coordinates visualization.

Install

# install package
npm install @lgv/parallel-coordinates

Data Format

The following values are the expected input data structure; id is optional. dimension. keys are arbitrary; however, they must match whatever values provided to dimensions during initialization if provided for an ordered arrangement.

[
    {
        "id": 1,
        "dimension1": 8,
        "dimension2": 6,
        "dimension3": 4
    },
    {
        "id": 2,
        "dimension1": 1,
        "dimension2": 2,
        "dimension3": 3
    }
]

Use Module

import { ParallelCoordinates } from "@lgv/parallel-coordinates";

// have some data
let data = [
    {
        "id": 1,
        "dimension1": 8,
        "dimension2": 6,
        "dimension3": 4
    },
    {
        "id": 2,
        "dimension1": 1,
        "dimension2": 2,
        "dimension3": 3
    }
];

// initialize
const pc = new ParallelCoordinates(data);

// render visualization
pc.render(document.body);

Environment Variables

The following values can be set via environment or passed into the class.

| Name | Type | Depcription | | :-- | :-- | :-- | | LGV_BRANDING | string | prefix used for dom element style names |

| Class | Element | | :-- | :-- | | lgv-parallel-coordinates | top-level svg element | | lgv-content | content inside artboard inside padding | | lgv-connection | curved path | | lgv-dimension | dimension label | | lgv-node | dimension value | | lgv-node-label | dimension value label |
