{"version":"1.0","type":"rich","title":"Task 3 Question3","description":"This stacked bar chart visualizes phone brand sales (Apple, Samsung, Xiaomi) across five countries, with each bar segment representing a brand's contribution to total sales. The chart uses D3.js v7 with SVG rendering, loading data from a CSV file. It employs `d3.scaleBand` for the categorical x-axis, `d3.scaleLinear` for the numeric y-axis, and `d3.stack` to compute stacked segments. Hover tooltips display exact sales figures per brand and country. A color-coded legend identifies each brand.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/55354032e5a944cfba5d930732117e49?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
