{"version":"1.0","type":"rich","title":"retail transactions","description":"This bar chart visualizes total sales revenue by product category from the `retail_transactions.csv` dataset. It loads data with `d3.csv`, aggregates the \"Total Amount\" field using `d3.rollups` and `d3.sum`, and renders the result as steel-blue bars. The chart uses `d3.scaleBand` for the categorical x-axis and `d3.scaleLinear` for the numeric y-axis, with rotated category labels and value labels above each bar. The SVG canvas is 900 by 520 pixels with specified margins.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c2a57068bc6240ca98c68e632201bbc9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
