Research direction
Examine the current polygon creation implementation in imglab, likely in the SVG related module. Review the svg.js documentation for methods to manipulate polygon points. Check the issue comments for any proposed solutions or discussions. Implement a function to append a point to an existing polygon element, ensuring compatibility with the existing annotation data model.
