{"version":"1.0","type":"rich","title":"Activity-6-Question-2","description":"A stacked bar chart shows the percentage of student ratings across six subjects, with each bar segmented into five rating bands from \"below 60%\" to \"above 90%\". The chart uses `d3.stack()` to compute the layered data and `d3.scaleOrdinal()` for color encoding. Interactive tooltips appear on mouseover, displaying the exact percentage for each segment. The visualization is rendered as an SVG with axes created via `d3.axisLeft()` and `d3.axisBottom()`, reading data from a local CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/24f4ce1b08ac41f79aae848d05ac8245?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
