{"version":"1.0","type":"rich","title":"Question 1: Bar Chart","description":"This bar chart visualizes total revenue aggregated by product from a CSV sales dataset fetched from a GitHub gist. Using D3 v7, it loads and processes the data with `d3.csv`, then applies `scaleBand` for the categorical x-axis and `scaleLinear` for the revenue y-axis. The SVG rendering includes value labels on each bar, rotated axis text, and a hover opacity transition. The bar chart displays a vertical layout with dollar amounts labeled, all within a styled container on a gradient background.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c428c6ad12854fa494c253e26af41027?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
