{"version":"1.0","type":"rich","title":"task2 question","description":"A stacked bar chart displays the percentage distribution of five rating levels across different vegetables, with each bar segment colored by rating category and totaling 100%. Hovering over a segment highlights it and reveals a tooltip with the exact percentage for that vegetable and rating level. The visualization uses D3 v7’s `d3.stack()`, `d3.scaleOrdinal`, `d3.scaleLinear`, and `d3.scaleBand` to encode data from a CSV file, rendering segments as SVG rectangles with mouse event handlers for interaction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c6bf7836b53045499319b5d8907170a7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
