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.
ts
import Ogma from '@linkurious/ogma';
const ogma = new Ogma({
container: 'graph-container'
});
Ogma.parse
.jsonFromUrl('solarCity.json')
.then(graph => ogma.setGraph(graph))
.then(() => ogma.view.locateGraph())
.then(() => {
console.log('import done');
});
