{"version":"1.0","type":"rich","title":"Top 1% share of income in selected countries","description":"The visualization tracks the share of national income held by the top 1% across twelve countries from 1910 to 2010, revealing divergent long-term trends such as the U-shaped pattern in the US and UK versus flatter trajectories in Denmark and Japan. It uses D3.js with an SVG line chart, where each country is drawn as a separate path via `d3.line` and `d3.axisBottom` for the time axis. The data comes from the provided CSV files, with missing values handled by filtering to a complete subset for the main series.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-334e1f73027e1a92254c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
