{"version":"1.0","type":"rich","title":"visualization7D3.js","description":"This multi-line chart displays the average first-semester grade by age at enrollment, with separate lines for male and female students. The visualization uses D3.js v7 to load the dataset via `d3.csv`, clean and aggregate the data with `d3.rollups` and `d3.mean`, and render the chart as an SVG. Points along each line include interactive tooltips showing gender, age, and average grade. Axes are generated with `d3.axisBottom` and `d3.axisLeft`, and a legend distinguishes the two gender groups.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/adb7f12d0a5747db8e888a4b78020296?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
