{"version":"1.0","type":"rich","title":"Activity6_population","description":"This example shows a horizontal bar chart of the populations of 20 countries in 2010, ordered by country name. The chart uses D3’s `scaleBand` and `scaleLinear` to map countries and population values to SVG rectangles, with axes built from custom React components. Population values are formatted with D3’s `format` function, converting values like “1.2G” to “1.2B”. The data is loaded asynchronously from a CSV file via `d3.csv`, and the rendering is done through React with SVG, using a light green fill for the bars and tooltips provided by SVG `<title>` elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/34247acd834e4c57a3c632e03c3b1e32?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
