Loopback Data Model Visualizer

The Loopback Data Model visualizer generates DOT or SVG diagrams from model definitions using graphviz.

To render models to graphviz diagrams such as DOT or SVG.

var schemaSvg = viz.render('Models', models, options);

fs.writeFile(path.join(__dirname, 'loopback-models.svg'), schemaSvg, function (err) {
  if (err) {
    throw err;
  }
  console.log('loopback-models.svg is saved to ' + __dirname);
});

var clsGraph = viz.renderGraph('Models', models, options);

fs.writeFile(path.join(__dirname, 'loopback-models.dot'), clsGraph, function (err) {
  if (err) {
    throw err;
  }
  console.log('loopback-models.dot is saved to ' + __dirname);
});
