The SVG-based visualizations, styled with CSS and built using D3 v7 APIs like `d3.rollup` and `d3.scaleBand`, show aggregate revenue by category, record-level units versus profit, monthly trends for three quantitative variables, and a dual-axis comparison of revenue (bars) with profit (line), complete with interactive tooltips.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bee8063b974c46769e56082887850806?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
