{"version":"1.0","type":"rich","title":"Tax revenue over time plot","description":"This scatter plot visualizes United States tax revenue as a percentage of GDP from 1800 to 2011, sourced from IMF historical data. Green circles encode each year, with axes for year and revenue share. The D3 v5 code uses `scaleLinear`, `axisBottom`, `axisLeft`, and `extent` to build the SVG chart, with explicit margins, gridlines, and rotated axis labels. Data is loaded via `csv` from a VizHub dataset, and styling uses comic-sans fonts and semi-transparent circles with black strokes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ad919ee2b4fd49ceae6d3b071cbc336f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
