{"version":"1.0","type":"rich","title":"activity6_Task1","description":"A horizontal bar chart displays the top 30 countries by 2020 population, with each bar’s length proportional to population and country names on the y-axis. The visualization uses React with D3 v5 to load CSV data via `d3.csv`, scale the values with `scaleLinear` and `scaleBand`, and render SVG rectangles through the `Marks` component. Axes are drawn with `AxisBottom` and `AxisLeft`, while tick labels are formatted using `d3.format` to abbreviate large numbers (e.g., “B” for billions). The chart's styling includes light green bars and blue axis lines.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8c4e8004ecd546cfa37598f00d38ce65?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
