{"version":"1.0","type":"rich","title":"question 1.1","description":"This example shows a horizontal bar chart ranking the populations of ten countries in the year 2000, using a dataset loaded via `d3.csv`. Green rectangles (`<rect>`) represent population values on a linear scale, with countries on a band scale and a formatted tick axis converting values to billions. Built with React and D3 v5, it uses `scaleBand`, `scaleLinear`, and `max` from D3 to compute scales, while `AxisBottom`, `AxisLeft`, and `Marks` are local ES6 modules rendering SVG elements. The chart includes a loading state and SVG tooltips via `<title>` elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7e72b25cc2f846acafdfab7446877074?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
