May I ask what I need to do to add a hyperlink to the graphic？

For example, the small rectangles below this website have hyperlinks added to each one. https://gosling.js.org/?example=BAM_PILEUP

Hi @TianYuanTuPo,

If you mean the tooltip, you can enable it by specifying the tooltip option:

"tooltip": [
  {"field": "start", "type": "genomic"},
  {"field": "end", "type": "genomic"},
  {"field": "insertSize", "type": "quantitative"},
  {"field": "svType", "type": "nominal"},
  {"field": "strand", "type": "nominal"},
  {"field": "numMates", "type": "quantitative"},
  {"field": "mateIds", "type": "nominal"}
],
