{"version":"1.0","type":"rich","title":"Activity 6 Question 1.2","description":"This example visualizes the 2010 population estimates for the top 20 countries as a horizontal bar chart, with each bar’s length proportional to population and tooltips showing the formatted value on hover. The visualization encodes country names along the y-axis and population along the x-axis, using green SVG rectangles rendered via React components. The implementation leverages d3’s `scaleBand` and `scaleLinear` for coordinate mapping, d3’s `csv` parser for data loading, and d3’s `format` for tick labeling (converting values to billions). The chart’s axes are custom-built with SVG, and the data is fetched from a CSV hosted on GitHub.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7e00fa5f66844fb9b8d184c38b410da0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
