{"version":"1.0","type":"rich","title":"Activity 6_Tutorial1","description":"This example displays a horizontal bar chart of the 2020 population for 30 countries, where each bar’s length encodes the numeric value and the y-axis lists country names. The visualization is built with React and D3 v5, using `d3.scaleBand` and `d3.scaleLinear` to map data to SVG rectangles. The data is loaded from a CSV file via `d3.csv`, and hover tooltips show formatted population values using `d3.format` with SI prefixes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/11c1b152d967439498d501e4d974e623?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
