{"version":"1.0","type":"rich","title":"The Margin Convention","description":"A bar chart displays population data for ten countries, encoded as horizontal rectangles whose widths scale with each country’s 2020 population. The visualization implements the margin convention by using a translation to offset an inner group from the SVG’s edges. React manages the rendering state, loading the CSV data via `d3.csv` and applying `scaleBand` for the categorical y-axis and `scaleLinear` for the quantitative x-axis. The chart demonstrates how to structure SVG output using React and D3 v7.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f70e7a8bb3b3459587a403b699b1723e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
