Research direction
The issue provides only an image and asks which method adds the outer ring; it includes no reproduction link, steps, chart type, or repository file. Start by identifying the chart and ring behavior shown in the image, then consult the relevant G2 API or examples. Done should mean a documented, reproducible method or a clarified issue with the missing details.
