{"version":"1.0","type":"rich","title":"Activity6_tutorial","description":"This bar chart displays the 2020 population estimates for 30 countries, sorted by country name. The visualization uses React with D3 v5’s `scaleBand` and `scaleLinear` to map data to SVG rectangles, with axes built from custom `AxisBottom` and `AxisLeft` components. Population values are loaded from a remote CSV and formatted with a SI prefix, replacing ‘G’ with ‘B’ for billions. Tooltips reveal exact values via SVG `<title>` elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/42e74de29bad4e48b5c8c53a62430709?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
