How to Create a Custom Report Visualization Type in ServiceNow or customize calendar type?

[AyanshN]

Hello Community,

I'm exploring the customization options in ServiceNow reporting. I would like to know if there is any way to create custom report visualization types, similar to the standard chart types like Donut, Pie, and Bar charts.

Additionally, I'm interested to know:

• Can we integrate external charting libraries such as Chart.js or D3.js into ServiceNow reports?
• Is there any scripting or configuration method to customize the report rendering?
• What are the best practices for developing custom report types without impacting system performance?

Any guidance, references, or documentation would be greatly appreciated.

Avoid running heavy reports during peak hours.
