{"version":"1.0","type":"rich","title":"Activity 6_tutorial1","description":"This horizontal bar chart displays the 2020 population estimates for the top 30 countries, with countries listed along the y-axis and population values mapped to bar length on the x-axis. The visualization uses a linear scale for population and a band scale for country categories, rendering light green bars as SVG rectangles via the `d3.scaleLinear` and `d3.scaleBand` APIs. The bottom axis includes a custom tick format that converts millions to billions (e.g., \"1.2B\"), and both axes are labeled. Data is loaded asynchronously from a CSV file using `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/98a0cd98b3094271995c2b071b96482b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
