The visualization uses D3 v7 APIs including `d3.csv`, `d3.group`, `d3.mean`, `d3.scaleLinear`, and `d3.line` to load, clean, and render the data as SVG. The interactive dashboard displays the data in a two-column grid layout with styled cards.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3bba939034c94411825b8ea08c560e51?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
