Grid

This example shows how to generate a grid using the grid method.

index.tsindex.htmlstyles.css

import Ogma from '@linkurious/ogma';

const COLORS = [
  '#161344',
  '#3f1c4c',
  '#632654',
  '#86315b',
  '#a93c63',
  '#cd476a',
  '#f35371'
];
const ROWS = 10;
const COLUMNS = 7;

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

const graph = await ogma.generate.grid({ rows: ROWS, columns: COLUMNS });

// Assign the graph to Ogma
await ogma.setGraph(graph);
await ogma.view.locateGraph();

document.getElementById('load')?.remove();

// Color by column
const colorValues = [];
for (let i = 0; i < COLUMNS; i++) {
  for (let j = 0; j < ROWS; j++) {
    const n = j * COLUMNS + i;
    colorValues.push(COLORS[i % COLORS.length]);
  }
}
ogma.getNodes().setAttributes(
  colorValues.map(color => ({ color })),
  250
);
