{"version":"1.0","type":"rich","title":"HW2 Iris Parallel Coordinate Plot Scale-Move","description":"This example shows the classic Iris dataset in a parallel coordinate plot, with four axes for sepal and petal measurements. A dropdown selector toggles the y-axis scale between a fixed global range (\"union\") and per-axis independent ranges (\"self\"), which visually emphasizes feature clustering differences. The code uses D3 v5 with `d3.scaleLinear` and `d3.extent` to compute scales, `d3.axisLeft` for tick marks, and `d3.drag` to reposition axes interactively. Semi-transparent polylines are colored by species, and axes can be reordered by dragging, with smooth transitions via D3's `.transition()` API.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/65a6ba37b6894c44886d41cd6904d0c3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
