The visualization uses D3 v7 to load CSV data from a GitHub gist, aggregate revenue by month and product name, and render an SVG chart with a categorical color scale, gridlines, and hover effects that increase stroke width and dot radius. The chart is presented on a gradient background within a styled card container, with a legend and axis labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4f43b52674bb42568829ad8005c8235f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
