Size

This example shows how to use the size attribute on nodes and edges texts.

index.tsindex.htmlstyles.css

import Ogma from '@linkurious/ogma';

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

ogma.styles.addNodeRule({
  text: {
    content: n => n.getId(),
    color: '#6a6',
    scaling: true, // if true, node text is proportional to node size
    size: node => 5 + +node.getId() * 5, // applied if scaling is false
    scale: node => 0.25 + 0.1 * +node.getId(), // applied if scaling is true
    minVisibleSize: 7
  }
});

ogma.styles.addEdgeRule({
  text: {
    color: '#0094ff',
    content: e => e.getId(),
    scaling: true, // if true, node text is proportional to node size
    size: 12, // applied if scaling is false
    scale: edge => 5 - +edge.getId(), // applied if scaling is true
    minVisibleSize: 3
  }
});

const graph = await ogma.generate.grid({ columns: 5, rows: 1 });
await ogma.setGraph(graph);
