{"version":"1.0","type":"rich","title":"activity 6_Task 1 ","description":"This interactive bar chart displays the 2020 populations of the top 30 countries, with each country’s value encoded as a horizontal bar’s length. Built with React and SVG, the visualization uses D3 v5 scales (`scaleBand` for the categorical axis, `scaleLinear` for the numeric axis) and `format` to abbreviate population labels (e.g., “B” for billions). Data is loaded asynchronously from a CSV via D3’s `csv` and parsed into numeric population values, with marks rendered as colored rectangles.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cb2778afcde345b8b7cdb7e692eec96a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
