{"version":"1.0","type":"rich","title":"activity6_q3","description":"This example presents a stacked horizontal bar chart visualizing mobile brand sales across four quarters. The data is loaded from a CSV file, and each brand’s quarterly sales are stacked to show total price contributions. The chart is rendered as an SVG using D3 v7, with axes, a title, and a color-coded legend. Hovering over a bar segment triggers a tooltip displaying the brand and its specific sales value. The visualization employs D3’s scaleBand, scaleLinear, stack, and axis functions to construct the layout and interactions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/666d6584346f4535b5a76af233b71eb1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
