{"version":"1.0","type":"rich","title":"The Margin Convention","description":"This example shows a horizontal bar chart of the ten most populous countries in 2020, with each bar’s length proportional to population. The visualization uses React to render SVG rectangles inside a `<g>` element translated by a margin object, while D3’s `csv` loads and parses the UN population data. `scaleBand` maps country names to vertical positions, and `scaleLinear` scales population values to bar widths within the inner chart dimensions. The chart omits axes and labels, focusing purely on the margin convention.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/db93c4cd09df4e078ef35a5d18623ab6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
