In my code below, I am able to draw a Treemap and also display the tag in each tree cell. But the text is overflowing the tile if it's a long word

I need to ensure the word stays in the tile even If it means putting .... after certain characters. How can I achieve them? Please have a look at the version of chart.js and Treemap I am using before providing the solution. Thanks a lot :)

  var topTags = [
  {tag:'android',num:42657},{tag:'reactjs',num:38844},{tag:'php',num:34381},{tag:'sql',num:29996},
];

var canvas = document.getElementById("treemap");
var ctx = canvas.getContext("2d");
var chart = window.chart = new Chart(ctx, {
  type: "treemap",
  data: {
    datasets: [{
      tree: topTags,
      key: "num",
      groups: ['tag'],
      spacing: 0.5,
      borderWidth: 1.5,
      fontColor: "black",
      borderColor: "grey"
    }]
  },
  options: {
    maintainAspectRatio: false,
    legend: { display: false },
    tooltips: { enabled: false }
  }
});
