{"version":"1.0","type":"rich","title":"activity 6","description":"This horizontal bar chart displays the 2020 population estimates for 30 countries, with bars sorted by country name along the Y-axis and population values on the X-axis. The visualization uses D3 v7’s `scaleBand` and `scaleLinear` to map data, while `d3.axisBottom` and `d3.axisLeft` generate the axes. SVG rectangles are rendered via a custom `Marks` component, and data is loaded asynchronously from a CSV using `d3.csv` with `autoType` parsing. The chart has a fixed 960×600 viewport with a left margin accommodating country labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6e7232d56c4945e9ab2140fa85592dd7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
