import Ogma from '@linkurious/ogma';

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

ogma.styles.addNodeRule({
  text: {
    color: 'blue',
    minVisibleSize: 5,
    content: n => 'Node ' + n.getId()
  }
});

ogma.styles.addEdgeRule({
  text: {
    color: 'grey',
    minVisibleSize: 3,
    content: e => 'Edge ' + e.getId()
  }
});

ogma.styles.setHoveredNodeAttributes({ text: { color: 'red' } });
ogma.styles.setSelectedNodeAttributes({ text: { color: 'red' } });
ogma.styles.setHoveredEdgeAttributes({ text: { color: 'red' } });
ogma.styles.setSelectedEdgeAttributes({ text: { color: 'red' } });

const graph = await ogma.generate.random({ nodes: 15, edges: 15 });
await ogma.setGraph(graph);
await ogma.view.locateGraph();
