{"version":"1.0","type":"rich","title":"Activity6_tutorial-1","description":"This visualization displays the top 30 countries by 2020 population using a horizontal bar chart rendered with SVG in a React application. The bars are populated from a CSV dataset, with population values formatted in billions using D3’s `format`. The chart uses `scaleBand` for the categorical country axis, `scaleLinear` for the quantitative population scale, and custom React components for the axes and marks. The code imports `csv`, `scaleBand`, and `scaleLinear` from d3.v5, while tooltips appear via SVG `<title>` elements on each rectangle.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/871c98c1d071494dad9b533988d62583?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
