{"version":"1.0","type":"rich","title":"D3 Introduction : Population Barchart","description":"This bar chart displays populations across countries in Asia, Europe, and the Americas, sorted alphabetically with a logarithmic color scale of steel blue bars. Built with D3 v5 within a React framework, it uses `d3.csv` to load `data.csv`, `scaleLinear` for the x-axis (converting values to billions via `d3.format`), and `scaleBand` for categorical y-axis spacing. Axis rendering relies on `axisBottom` and `axisLeft`, with the SVG viewport sized at 900×500 pixels and margins configured for label placement.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9473b4a172c1468d9d6fee07ba3c229c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
