{"version":"1.0","type":"rich","title":"Actvity6_task1","description":"This example shows a horizontal bar chart of 2020 population estimates for 30 countries, using SVG rectangles scaled by population values. The visualization loads CSV data from a GitHub repository via `d3.csv`, processes it with a row conversion function, and renders React components. The code uses D3 v5 scale functions (`scaleBand`, `scaleLinear`), `d3.format` for tick labeling (converting values to billions), and custom axis components that generate SVG tick marks and text labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/132239524c444ad593dc50d19fe890a9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
