Question

I’m using a Highcharts tree graph chart. I managed to enable the scrollbar with some help. Another thing I’m trying to do but keep failing is to be able to move on the graph like on Google maps and zoom in and zoom out with scroll wheel.

I might have wrote the correct JS but then didn’t have right CSS or had a CSS that made the code no work.

Highcharts.chart('container', {
  chart: {
    spacingBottom: 150,
    marginRight: 120,
    // margin: [50, 50, 50, 50], // Top, right, bottom, left
    height: 3500,
    width: 2500
  },
  title: {
    text: 'Phylogenetic language tree'
  },
  series: [{
    type: 'treegraph',
    keys: ['parent', 'id', 'level'],
    clip: false,
    data: [
