JSON

This example shows how to import a graph from a JSON file into an Ogma visualization. It uses the jsonFromUrl method to load the graph data from a JSON file retrieved over HTTP. The content of the file is available here.

import Ogma from '@linkurious/ogma';

const ogma = new Ogma({
  container: 'graph-container'
});

Ogma.parse
  .jsonFromUrl('files/solarCity.json')
  .then(graph => ogma.setGraph(graph))
  .then(() => ogma.view.locateGraph())
  .then(() => {
    console.log('import done');
