{"version":"1.0","type":"rich","title":"question2","description":"This example displays a horizontal bar chart comparing the populations of 20 countries in 2010, using React to render SVG elements. The code imports `scaleBand`, `scaleLinear`, and `max` from d3 to position bars and axes, with custom `AxisBottom`, `AxisLeft`, and `Marks` components. Population values are parsed from a remote CSV file using d3’s `csv` function and formatted with `.2s` notation (displaying billions as “B”). Bars are drawn as SVG rectangles with tooltips showing formatted values, and axes use blue tick lines and gray text.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7906f65b0c4f4021a801a8eb64a4948e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
