{"version":"1.0","type":"rich","title":"Untitled","description":"This example shows a line chart of FRED data over time, displaying a single series of values with a time-based x-axis and linear y-axis. The visualization is rendered as an SVG within a React framework, using D3 v7 to load CSV data, parse dates, and generate the axes and line path. The chart uses `d3.scaleTime`, `d3.scaleLinear`, and `d3.axisBottom`/`d3.axisLeft` to map the data, while the CSV is fetched from a GitHub gist URL. The page also includes a navigational header with dataset and about links.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b163deaff04043e7b696636da76319bc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
