{"version":"1.0","type":"rich","title":"activity 6 task 1","description":"This horizontal bar chart displays the 2020 populations of 30 countries, sorted from largest to smallest. The visualization loads data from a CSV file via `d3.csv`, processes it with React state management, and renders the chart using SVG. D3’s `scaleBand` and `scaleLinear` map countries to horizontal bars, while custom React components (`AxisBottom`, `AxisLeft`, `Marks`) generate the ticks and rectangles. The x-axis labels are formatted using `d3.format` with a custom function that converts gigabytes to billions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/574700f6d86b44388f37a204f5e50412?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
