{"version":"1.0","type":"rich","title":"Activity 6_Question 2","description":"This stacked bar chart visualizes sales figures for Grocery, Appliances, and Toys across three years (2018–2020), with each bar segment colored by category. Built with D3.js v7, it uses `d3.stack` to accumulate category values, `d3.scaleBand` and `d3.scaleLinear` for axes, and SVG rectangles for rendering. Interactive tooltips appear on mouseover, displaying category and exact sales amount. The chart includes axis labels, a legend, and reads data from a local CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4278fae2eb9b4af9b91cc96bddc3fc93?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
