• Documentation: Extensive and well-maintained documentation is available on the official Chart.js website. This should be your first port of call.
• GitHub Issues: Report bugs, suggest enhancements, or ask questions by creating an issue on the official GitHub repository. This is where developers working on the project are active and can often provide solutions.
