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 3d scatter chart using highcharts library with examples.
Following is the example of creating a 3D scatter chart by setting the required chart properties using highcharts library.

If you observe the above example, we created a 3D scatter chart 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 3D scatter chart using highcharts library with required properties.
