{"version":"1.0","type":"rich","title":"Activity6_Task1","description":"This bar chart displays the 2020 population estimates for 30 countries, arranged vertically with bars extending horizontally from a shared origin. The visualization uses a React component with D3 scale functions (`scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis), rendering SVG rectangles via the custom `Marks` component. Data loads asynchronously from a CSV file using D3’s `csv` parser, with axis ticks formatted using `format('.2s')` to abbreviate large numbers. A tooltip appears on each bar through an SVG `<title>` element.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/27a6dc5a7689443ea71864b62387d4ff?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
