Hovering over a marker displays a tooltip with the exact age and grade value. The visualization loads CSV data from a GitHub repository, processes it with `d3.rollups` and `d3.mean` to aggregate averages per age, and renders the chart as SVG using `d3.line`, `d3.scaleLinear`, and `d3.axisBottom`/`d3.axisLeft`. A custom legend distinguishes the two grade series.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f9025564f6b44c34913b53ad263bac55?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
