{"version":"1.0","type":"rich","title":"Expenditure over time plot","description":"This plot shows United States expenditure as a percentage of GDP since 1800, with a red line charting the yearly values. The visualization uses D3.js v5, scaling the x-axis linearly for years and the y-axis linearly for expenditure percentages. It renders as SVG, with the line generated using `d3.line`, `curveBasis` for smoothing, and axes created via `axisBottom` and `axisLeft`. Data is loaded asynchronously from a CSV file using `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b4811da10785419086922f96da832cf0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
