{"version":"1.0","type":"rich","title":"Activity_6_tut-1","description":"A horizontal bar chart displays the 2020 population for the top 30 countries, sorted by country name with bars extending left-to-right. The visualization uses React with D3 v5's `scaleBand` for the y-axis and `scaleLinear` for the x-axis, rendering SVG rectangles via the `Marks` component. Population values are loaded from a CSV, formatted with `d3.format`, and converted from raw numbers to billions using a custom tick formatter that replaces 'G' with 'B'. The chart includes styled axis ticks, a labeled x-axis, and tooltips showing the formatted population on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a8566638b76f4c30961ba3d6eadd399e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
