{"version":"1.0","type":"rich","title":"Assignment 6","description":"This bar chart shows total sales aggregated by product line, using a simple grouped bar layout where each bar’s height encodes the summed sales value. The chart is built with D3 v7, loading data from a CSV file and using `d3.rollup` to group and sum sales per product category. SVG rectangles are scaled with `d3.scaleBand` and `d3.scaleLinear`, with axes generated via `d3.axisBottom` and `d3.axisLeft`. The title and rotated x-axis labels complete the visualization, rendered entirely in SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4ab5bff61aa44514ad1997b4f1d3112e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
