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 tree map with levels using highcharts library with examples.
Following is the example of creating a tree map chart with levels by setting the required chart properties using highcharts library.

If you observe the above example, we created a tree map chart with levels 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 tree map chart with levels using highcharts library with required properties.
