{"version":"1.0","type":"rich","title":"d3.js practice","description":"A bar chart displays population estimates for ten countries, using horizontal bars ordered from China’s 1.4 billion down to Mexico’s 130 million. The visualization loads a CSV file via `d3.csv`, converts the population strings to numbers, and renders SVG rectangles with `d3.scaleLinear` for the x-axis and `d3.scaleBand` for the categorical y-axis. Data binding appends rects, while `bandWidth()` sets each bar’s height, with no axes or labels shown.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/629d495041f4410cb236d748822060f2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
