{"version":"1.0","type":"rich","title":"Making a Multiline Chart","description":"Eight weeks of simulated playoff power rankings are shown as eight colored, semi-transparent lines, one per team, across the x-axis (week) and y-axis (power rank). Hovering over a line thickens it and increases its opacity. Built with D3 v5, it uses `d3.line()`, `d3.nest()`, `d3.scaleOrdinal()`, and a custom legend from `d3.axisLeft()` calls, reading the `data.csv` file. Lines are drawn as SVG paths, and hover effects use D3's `.transition()` for animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c018b846341e4984a9300ade48dade30?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
