{"version":"1.0","type":"rich","title":"Activity 6 Tutorial 1","description":"This example presents a horizontal bar chart showing the 2020 population for 30 countries. The visualization uses D3 v5 for data loading and scaling, with React components for rendering each SVG element. D3’s `scaleBand` and `scaleLinear` map country names and population values to pixel positions, while custom `AxisBottom`, `AxisLeft`, and `Marks` components generate the tick marks and bar rectangles. The data is fetched from a CSV file using D3’s `csv` function, and tooltips display formatted population values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/21d6a3a9e0584b76928c0ecf0122ae1a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
