{"version":"1.0","type":"rich","title":"Activity 7_Task1","description":"This visualization displays the 2020 populations of 30 countries as a horizontal bar chart, using bar length to encode population values. It is rendered as an SVG using React components and D3 v5, specifically leveraging D3's `scaleBand` for the categorical y-axis, `scaleLinear` for the continuous x-axis, and `format` for tick labels that abbreviate large numbers (e.g., \"B\" for billions). The code imports data via D3's `csv` parser from a GitHub-hosted CSV file, and it constructs the chart with custom React components for axes and marks.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bbeaa14e5339456db9d6d2fa9701b7b9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
