{"version":"1.0","type":"rich","title":"Gist c7d6ce69974576c130ef","description":"This example converts Node.js V8 log files into symbolicated perf maps for generating flame graphs. The `convert.js` script parses code-creation events from the v8 log, extracting the instruction start address, length, type, and function name to produce entries in the format expected by Linux perf. The workflow uses `fs.readFileSync` and `split` to process the log, then pipes the output to a perf map file. The resulting visualization shows CPU sampling data from `perf record` as a flame graph, enabling performance analysis without upgrading Node.js.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-c7d6ce69974576c130ef?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
