{"version":"1.0","type":"rich","title":"Activity6_quiz 1.2","description":"A horizontal bar chart ranks the world's top 20 most populous countries by their 2010 population, using a teal fill for each bar. Built with React and D3 v7, the chart uses `d3.scaleBand` for the categorical y-axis and `d3.scaleLinear` for the quantitative x-axis, formatting tick labels as millions. It loads a CSV dataset from a GitHub gist, with fallback sample data if fetching fails, and renders the visualization as an SVG with custom axis components.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4f9358de61364dcbba4d101e66062370?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
