{"version":"1.0","type":"rich","title":"Gist 9442b080af40909ec71d","description":"This animation visualizes performance data collected from a development tools session. The code periodically dumps accumulated performance metrics to a file, writing each batch of records as comma-separated JSON objects appended to `devtools.json`. It uses `fs.appendFile` to write data every 3 seconds, managing the first-write flag to properly format the array. The visualization relies on a global `perfs` array that stores performance entries, which are serialized and output without any charting or rendering library.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-9442b080af40909ec71d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
