{"version":"1.0","type":"rich","title":"Activity 6_Task 1","description":"This example shows a horizontal bar chart of the 20 most populous countries in 2010, with population values on the x-axis and country names on the y-axis. It uses React with D3 v5’s `scaleBand` and `scaleLinear` to position bars, while custom `AxisBottom` and `AxisLeft` components render tick marks and labels. Data is loaded asynchronously from a CSV via `d3.csv` and `useEffect`, with population converted from thousands. A `Marks` component draws each rectangle and includes a `title` element for hover tooltips.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cd003eb57ae844d3a66485ffb97da3f1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
