{"version":"1.0","type":"rich","title":"环境性能数据随时间变化线性图","description":"This visualization shows how three system performance metrics—I/O, network, and CPU—vary over a sequence of 46 timestamps. Three smooth curved lines, generated with the D3 `line()` generator and a monotone X curve, represent each metric across the timeline, with colored dots marking individual data points. The chart uses `d3.scaleLinear` for both axes and renders to SVG. The code computes the line paths and point positions from a CSV file and includes hover tooltips that display the exact timestamp and percentage value for each point.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/97081182f2ab4459b6f7fc8324836102?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
