The visualization loads data from a CSV file and renders it with SVG using d3.v7, applying d3.line for the paths, d3.axisBottom for the x-axis, and d3.legend for a color legend. Hovering over a circle highlights it in orange and displays a tooltip with the year, CPI value, and grain type. The chart includes labeled axes and a title.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5397762c89a7414682bb3ce931f0453c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
