{"version":"1.0","type":"rich","title":"final project","description":"This bar chart shows the average grades of students grouped by their self-reported stress levels (Low, Medium, High). The visualization uses d3.csv to load a remote dataset, d3.rollup to aggregate the grade means, and d3.scaleBand with d3.scaleLinear to map stress categories and grade averages to the SVG coordinate system. Bars are rendered as SVG `rect` elements, with axis labels and rotated x-axis tick text for readability. The chart highlights the relationship between mental health and academic performance.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/80b65c1c8f0c422e83b89d2c5b056ff2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
