Summary
A new Dashboard widget that visualizes Zabbix Services hierarchy using a Sunburst chart.

Problem
Current dashboard widgets do not provide a clear hierarchical visualization of Services and their aggregated states.

Solution
A Sunburst-based widget that:

• Represents service hierarchy
• Reflects service status aggregation rules
• Highlights incidents visually
• Supports labels and tooltips

Compatibility

• Tested on Zabbix 7.2
• Implemented as a standalone widget module
• No core patches required

Status
The widget is fully implemented and available for review.
I can provide a Pull Request if there is interest in upstreaming it.
