{"version":"1.0","type":"rich","title":"d3-timer memory leak","description":"This example demonstrates a memory leak in d3-timer by creating a timer that runs indefinitely with a 150-millisecond delay. The page loads the d3-timer library from a CDN and instantiates a timer via `d3.timer()`, passing an empty callback that executes on each tick. The visualization shows how a timer persists without explicit disposal, highlighting potential performance issues in long-running applications. The code uses plain HTML and JavaScript with no rendering, making the leak’s behavior visible through browser developer tools rather than visual output.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7ee7c789a23744129d4ea8e7857cbf88?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
