{"version":"1.0","type":"rich","title":"Activity6_Q2","description":"This stacked bar chart shows customer satisfaction levels across ten car brands, with each bar segmented into five rating categories from “Very Dissatisfied” to “Very Satisfied.” Hovering over a segment displays its exact count via a tooltip. The visualization uses D3 v7’s `d3.stack()` to compute stacked layers, `d3.scaleOrdinal()` for color mapping, and `d3.axisLeft()` and `d3.axisBottom()` for axes. Data comes from the embedded `car_data.csv` file, and the SVG rendering includes a legend and axis labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/471d038af8514c73a91f1ce657f9a14c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
