{"version":"1.0","type":"rich","title":"Activity6-Tutorial","description":"This example shows a horizontal bar chart of 2020 population figures for 30 countries, with bars colored light green and a blue axis. It uses React with D3 v5 scales—`scaleBand` for the categorical country axis and `scaleLinear` for the population axis—to render SVG rectangles via the `Marks` component. Axis labels are generated with custom `AxisBottom` and `AxisLeft` components, and population values are formatted using D3’s `format('.2s')` to display abbreviations like \"B\" for billions. Data is loaded asynchronously from a CSV file via `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b38229c6fe134f82b55a2ffe3334b17f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
