{"version":"1.0","type":"rich","title":"Activity 6 Question 2","description":"This example shows stacked bar charts of sales in dollars across three product categories—Electronics, Furniture, and Clothing—for the years 2018 through 2020. It uses D3 v7 with the `d3.stack` API to layer the series, `d3.scaleBand` for the yearly bars, and `d3.scaleLinear` for the y-axis. Hovering reveals a tooltip with the category and exact value, while a legend identifies each color from `d3.schemeCategory10`, as loaded from a local CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/75769df3387046cfa6e4649fdf1a8b5e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
