{"version":"1.0","type":"rich","title":"HTML Starter","description":"This example renders a dual-axis time series chart of S&P 500 stock prices and long-term interest rates from monthly data in a CSV file. The SVG visualization uses D3 v5 scales and axes, with two line generators for each metric and a filled area between them, though the area is nearly transparent. The chart displays the data over time with inverted y-axes and employs `d3.csv` for data loading and `scaleTime` for temporal mapping.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4f4186d7ae5e442e8b6405bd030defda?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
