{"version":"1.0","type":"rich","title":"Customized Line Chart","description":"This line chart displays federal budgetary resources over time, with dropdown filters for agency and account name and checkboxes to toggle comparison lines from related accounts. The SVG visualization renders a natural curve path and individual data points using D3 scales and the `line().curve(curveNatural)` generator, while React manages the interactive state. A CSV dataset is loaded via `d3.csv` and processed with `d3.rollup` to aggregate quarterly sums. Axes are custom-built with D3 time and linear scales, and tooltips appear via SVG `<title>` elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a919d99cccf94458b919c84aef7aeeb3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
