import Ogma from '@linkurious/ogma';
const ogma = new Ogma({

ogma
.addNodes([
{ id: 'n1', attributes: { x: -40, y: 20, color: 'magenta' } },
{ id: 'n2', attributes: { x: 0, y: -30, color: 'orange' } },
{ id: 'n3', attributes: { x: 40, y: 20, color: 'orange' } }
])
.then(() => ogma.view.locateGraph());
setTimeout(() => {
ogma
.addNode({
id: 'n0',
attributes: { x: 0, y: 0, color: 'green', radius: 20 }
})
.pulse({ width: 5, duration: 1000 });
