This short guide explains the process to create a Sunburst chart using Java in an Excel file. It provides steps for writing the application and a sample code for a Sunburst chart generator using Java. Details are also provided to configure the chart parameters and customize its visualization as per the requirements.

Steps to Create a Sunburst Chart using Java

1. Establish the environment to use Aspose.Cells for Java to create a Sunburst chart
2. Load or create a Workbook having hierarchical data for a Sunburst chart
3. Set headers for the data and fill sample data if not available
4. Add a Sunburst chart in the sheet and set its title
5. Configure the data series, category hierarchy, title, and visual style of the chart
6. Customize the chart visual style as per requirements
7. Save the output Sunburst chart Workbook on the disk

This list of steps encompasses the complete process to develop a Sunburst chart creator using Java. Load or create a Workbook with the specified data for the chart with appropriate headers and hierarchical data, create a Sunburst chart, and set data series, category hierarchy, title, and visual style in it. Save the updated Workbook on the disk with data and a chart in it.

Code to Create Sunburst Chart using Java

The above sample code demonstrates the process to develop a Sunburst chart maker using Java. This code contains sample data; however, you can also load an existing Excel file with appropriate hierarchical data for the chart. Notice the conversion of the last column to a double value, as placing the string data here will not create a Sunburst chart.
