{"version":"1.0","type":"rich","title":"Fork of Dual Y-Axes","description":"This visualization plots the S&P 500 index and the long-term interest rate over time as two separate lines, each with its own y-axis scale, on a shared time-based x-axis. A faint gray area fills the space between the two lines, suggesting a comparison of their relative movements. The chart is built using D3 v5 within a React framework, relying on `d3.line`, `d3.area`, `d3.scaleTime`, and `d3.scaleLinear` to render the SVG elements, with data loaded from a CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f84d1610405f4555a6ef1ebeb0aa18f7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
