Usage options

Lightning server

The Lightning server provides API-based access to reproducible, web-based visualizations. It can be deployed in many ways, including Heroku, Docker, a public server, a local app for OS X — and even a server-less version well-suited to notebooks like Jupyter. It comes bundled with a core set of visualizations, but is built to support custom ones.

Read more about getting started with a Lightning server

You can create an adjacency visualization using Python, Scala, JavaScript, or R by using API clients for making requests to a Lightning server.

Clients

Take a look at each client for installation and usage examples:

Python adjacency example

from lightning import Lightning
from numpy import random
 
lgn = Lightning()
 
mat = random.rand(10,10)
mat[mat < 0.75] = 0
group = (random.rand(10) * 5).astype('int')
 
lgn.adjacency(matgroup=group)

Scala adjacency example

import org.viz.lightning._
import scala.util.Random
 
val lgn = Lightning()
 
val mat = Array.fill(10)(Array.fill(10)(Random.nextDouble()).map{ d =>
    if (d < 0.75) {
        d
    } else {
        0.0
    }
})
val group = Array.fill(10)(Random.nextInt)
 
lgn.adjacency(mat, group=group)

JavaScript module via npm

lightning-adjacency is an npm module that can be used on its own.

Install as JavaScript module

npm i --save lightning-adjacency

Example

var Adjacency = require('lightning-adjacency');
 
var el = document.createElement('div');
document.body.appendChild(el);
 
var data = {
  nodes: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
  group: [0, 0, 1, 1, 1, 1, 2, 2, 2, 2, 2],
  links: [[0, 1, 1], [0, 2, 1], [1, 3, 3], [5, 6, 4], [7, 9, 2]],
  labels: ["name 0", "name 1", "name 2", "name 3", "name 4", "name 5", "name 6", "name 7", "name 8", "name 9", "name 10"]
};
 
var options = {
  numbers: true,
  symmetric: true,
  sort: 'group',
  width: 600,
  height: 400
};
 
var adjacency = new Adjacency(el, data, options);

API

var Adjacency = require('lightning-adjacency');

var adjacency = new Adjacency(selector, data, options);

Arguments:

  • selector – css selector or dom node that will act as parent node of the visualization
  • data – the required data for the Visualization
    • nodes – array representing nodes in the visualization
    • group – array representing groups
    • links – array of arrays describing the links between nodes
    • labels – array of strings
  • options
    • widthNumber – the width of the visualization
    • heightNumber – the height of the visualization
    • numbersBoolean – Set to true to show numbers in cells of the visualization. Default: false
    • symmetricBoolean
    • sort – can be either group or degree
