{"version":"1.0","type":"rich","title":"5. Vega-Lite API Template","description":"This visualization shows the relative gains of companies, plotting each as a circle whose size corresponds to weight and whose color indicates whether the gain is positive or negative. The chart is built with the Vega-Lite API, which registers Vega and Vega-Lite and renders an SVG view. Data is fetched as JSON from a gist and processed with D3’s `fetch` and `map` methods, while tooltips and axis styling are configured through the API. The visualization uses a dark-themed custom config to improve readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/35a3c7fc4c99451ab520ad97a1e16dd6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
