{"version":"1.0","type":"rich","title":"Question 1.1","description":"A horizontal bar chart displays the 2010 populations of twenty countries, loaded from a remote CSV with D3's `csv` function. React renders SVG rects for data marks, with a linear scale mapping population to bar width and a band scale mapping country names to vertical positions. D3's `format` function abbreviates tick labels, replacing 'G' with 'B' for billions in the bottom axis. Mouseover tooltips, created with SVG `<title>` elements, show the formatted population values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e4491db0a8554a39925ddb418b88ca5f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
