{"version":"1.0","type":"rich","title":"question 3(task 2)","description":"This example shows average subject scores in math, science, and English for five schools, displayed as a horizontal stacked bar chart. Each bar segment represents a subject’s contribution to the total score, with a color legend identifying the subjects. The visualization uses D3 v7 to load CSV data, apply a stack layout, and render SVG rectangles scaled by linear and band scales. Axes, a total-score axis label, and an interactive-free legend are drawn using D3’s axis and ordinal color APIs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/37544e843ecc4a8f9e575f895d4c76c0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
