{"version":"1.0","type":"rich","title":"Refactored Iteration Line Graph: vgsales.csv","description":"This interactive small-multiple chart displays video game sales over time across five regional markets, with each facet corresponding to a sales category (global, North America, Japan, EU, and other). A legend color-codes twelve genres, allowing users to hover to highlight a genre’s lines or click to toggle its visibility. Built with D3 v6, the SVG visualization fetches data from a GitHub gist and aggregates sales by year and genre via `d3.flatRollup` and `d3.sum`. Users can pan by dragging, zoom with the mouse wheel, and reset the view, while axes dynamically redraw their domains using `d3.axisBottom` and `d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bb25787fb96f4b4883d5ec972cafdad6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
