{"version":"1.0","type":"rich","title":"Activity6_task1","description":"This horizontal bar chart displays the 2020 populations of 30 countries, sourced from a CSV file. The visualization uses D3.js (v7) and renders through SVG. A linear scale maps population values to bar widths, while a band scale positions countries along the vertical axis. The code explicitly creates light green bars via `Marks.js` and formats the population labels in billions using `d3.format` within `AxisBottom.js`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c76d013bb8da4bd1bd91a759b26a5c4f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
