{"version":"1.0","type":"rich","title":"The Margin Convention","description":"This example shows the top 10 most populous countries as a simple bar chart, with each country’s population represented by the width of a rectangle. The chart deliberately omits axes, ticks, and labels to highlight the importance of margins in visualization layout. Built with React and D3 v5, it uses `scaleBand`, `scaleLinear`, and `max` to map data to screen coordinates, while a fixed margin object reserves space around the SVG. Data comes from the United Nations World Population Prospects 2019, rendered entirely as SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/37865a008bfb4785a073de294271b93c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
