{"version":"1.0","type":"rich","title":"环境性能数据随时间变化线性图","description":"This visualization displays how three system performance metrics—I/O, network, and CPU utilization—change over a 45-second time interval. The data, sourced from a CSV file, is plotted as smoothed line charts using D3 v5’s `line()` and `curveMonotoneX` to create smooth curves. Each metric is represented by a distinct colored line and accompanying circular scatter points, with hover tooltips revealing exact percentage values. The chart is rendered as an SVG, with axes created via `axisBottom` and `axisLeft`, and it includes a manual legend at the top.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/61e2f43e25934f129c3b753ff59fdff1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
