{"version":"1.0","type":"rich","title":"q3-ice7","description":"This example shows a line chart of average scores for three subjects—Math, Reading, and Writing—derived from the StudentsPerformance dataset. It uses D3 v7 with SVG rendering, loading CSV data via `d3.csv`, then computing means with `d3.mean`. The chart employs `d3.scalePoint` for the categorical x-axis, `d3.scaleLinear` for the y-axis, and `d3.line` to draw the trend line, with red circles marking each average score.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cbd024f133254eaa87add2e0b6a3a13f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
