{"version":"1.0","type":"rich","title":"activity 6_Task 1","description":"This visualization displays population data for 30 countries in 2020 as a horizontal bar chart, with country names on the y-axis and population values on the x-axis. The chart uses React to render SVG elements, with D3 v5 providing the scale functions (`scaleBand`, `scaleLinear`) and CSV data loading via `d3.csv`. Data is sourced from a GitHub-hosted CSV file, formatted with the `d3.format` function to abbreviate large numbers. The gradient bars are colored light green, and hovering reveals population values through native SVG tooltips.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/48bf66e59be34a5d947eea05a9051f4b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
