In the previous chapters, we learned how to setup highcharts library and how to create a chart with required configurations using highcharts library in our webpage. Now, we will learn how to create a word cloud chart using highcharts library with examples.
Following is the example of creating a word cloud chart by setting the required chart properties using highcharts library.

$(function() {
var text = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean bibendum erat ac justo sollicitudin, quis lacinia ligula fringilla. Pellentesque hendrerit, nisi vitae posuere condimentum, lectus urna accumsan libero, rutrum commodo mi lacus pretium erat. Phasellus pretium ultrices mi sed semper. Praesent ut tristique magna.

var lines = text.split(/[,\. ]+/g),
data = Highcharts.reduce(lines, function(arr, word) {
var obj = Highcharts.find(arr, function(obj) {
return obj.name === word;
});
if (obj) {
obj.weight += 1;
} else {
obj = {
name: word,
weight: 1
};
arr.push(obj);
}
return arr;
}, []);
Highcharts.chart('container', {
series: [{
type: 'wordcloud',
data: data,
name: 'Occurrences'
}],
title: {
text: 'Wordcloud of Lorem Ipsum'
}
});
});
</script>
</head>
<body>
<div id="container"></div>
</body>
</html>
If you observe the above example, we created a word cloud chart by using highcharts library with required properties.
When we execute the above highcharts example, we will get the result like as shown below.
This is how we can create a word cloud chart using highcharts library with required properties.
